I think if there’s one thing that truly captures the majesty and luxury of an RV, camper, or motorhome, it’s the fact that such vehicles are uniquely equipped with the means to allow you to take a leisurely, comfortable, involved, unhurried bowel movement anywhere, anytime, from within the comfort of your vehicle. There’s simply no greater luxury in the automotive world; the finest Rolls-Royce Phantom, for all its elegance and refinement and status, would become a fetid, unwelcoming nightmare-box were one to take a simple, basic shit in the back seat. For want of a toilet and bathroom, the Rolls-Royce, compared to any RV so equipped, is garbage.
That’s why when I went to that big RV show in Elkhart, Indiana earlier this week, as a guest of THOR, who kindly let me check out many, many motorhomes and RVs in their Open House area, I took advantage of the opportunity to really evaluate the current state of the art regarding Motorhome, RV, and trailer bathrooms, from the perspective of a dedicated defecator.

While I tried out a lot of bathrooms in a lot of different models, I think it would be cumbersome to try and do a model-by-model breakdown, partially because there are so many damn models and the differences can be so minor and Byzantine, it just doesn’t make sense. The bathroom layouts tend to be more standard across bigger categories of vehicle, so I’ll give my reviews for the following categories: Class B, with a subclass for Sprinter-based and Ram Promaster-based; Large-Scale Rear-Engined Motorhome (usually thought of as diesel pushers, but there are gasoline ones, too); and Class C motorhomes.
There are more categories that can be done, of course, and as I get more opportunities, I will avail myself of them. But this feels like a good start.
For testing criteria, we need some metrics. I propose the following set of defecation-enthusiast-bathroom-evaluation criteria:
Physical Comfort: This covers the toilet itself, and how it feels to be perched upon it. Can you comfortably sit on this toilet for the potentially extended duration of your poop? Is there adequate room for your legs and other limbs? Can you maneuver effectively with the door closed for wiping and other hygiene purposes?
Emotional Comfort/Security: Many people only feel comfortable taking a leisurely dump within the confines of their own homes. Can this mobile setup approach that level of emotional security and comfort? Does it feel private enough, and free from both visual and auditory contact? Can you truly relax in this environment to allow your bowels to fully expunge their foul contents?
Amenities: What, in addition to the toilet, is available? Is there a sink inside the bathroom, or do you need to exit to use one? If it is a wet bathroom, how much does the toilet area affect the use of the shower, and vice-versa?
Emergency Use Viability: If you eat something that reacts violently to your system, how well will this work for worst-case defecation events? Are there grab handles? Effective flushing systems? Good soundproofing to muffle screams and other noises?
Those seem to cover the important things, right? Oh, and here was my test procedure. Initially, the plan was to eat between six to twelve fast-food burritos every three hours and use each bathroom to the fullest possible extent. Unfortunately, a group of nosy dealers happened upon me as I was attempting to execute my first test and loudly and somewhat rudely demand I cease production and threatened to call the authorities should I introduce any foreign material into their pristine black water tanks.
They then flung me out of the Class A I was in, and onto a small group of recycling bins, which made a truly alarming cacophony of sounds when I flopped onto them.
So, I revised my test procedure. Because of the small-minded, anti-science element, I decided to simply mimic the actions of a healthy bowel movement instead of actually crafting one for every toilet. So, I sat on the toilet, adjusting my body for most accurate positioning, moved, grunted, strained, and so on in the best possible approximation of the act I could manage.
Okay! On to the evaluations!
Class B, Sprinter
Class Bs are the smallest of the classes, and a very popular class right now. These may be the smallest self-propelled camping solutions to contain an actual bathroom. Currently, these are usually based on either Mercedes-Benz Sprinter vans or RAM Promaster vans. I tried both.
First, let’s try this Mercedes-Benz model, targeted at the overlanding community.
It has a small, fully enclosed wet bathroom that may be the minimum possible size for a bathroom. Here’s how I fit on the toilet, and remember, I’m a very compact person:
Okay, evaluation time:
Physical Comfort: This is tricky, mostly because of the size of the bathroom itself. It’s basically a stall shower with a toilet, and with the door closed, it is extremely difficult to fit your legs in there. I suspect many people will opt to poop in here with the door open and their legs outstretched, but that’s unacceptable unless you’re completely alone. With the door closed, I also felt I was being pushed back on the seat of the toilet to a non-optimal point for comfortable shitting. Overall, marginal.
Emotional Comfort/Security: There’s actually a very crude and simple lock on the upper part of the door that seems at first somewhat half-assed, but I think it’s actually a big benefit, because you can very easily see that it’s secure and you can see if it moves, indicating attempted entry.
This helps comfort and security a good bit. What’s less good is the uncomfortable knowledge that you’re a 1/4″ thick sheet of thin veneered particle board away from whomever else is in the van, possibly preparing something in the little kitchen area just on the other side of the door. All sounds and screams and moans are easily heard.
Amenities: There’s no sink in here, just the showerhead, which I suppose you could try to use for hand washing, but you’ll likely get soaked.
Emergency Use Viability: Better than nothing, but not ideal.
Class B, Promaster
There’s another popular Class B platform, the RAM Promaster, and I found a number of these that located the bathroom in a different area of the van: at the rear, as opposed to the middle, as in the example above. Here’s the layout:
Physical Comfort: Actually, quite good! It’s a very small area, but the space is used well, and the perpendicular to the long axis of the van setup is effective here. The slight rise the toilet is mounted on helps comfort as well, and access to the toilet paper holder is excellent, too.
Emotional Comfort/Security: The setup has its biggest faults here; even though the window is tinted black on the outside, that large window right by your head while you’re crafting a top-tier mass of waste is unsettling, at best. Yes, there is a curtain, so this issue is mitigated, but your head is right by that window, and if you’re pooping in, say, a parking lot and someone comes up to check their appearance in that mirrored rear glass, you’re going to have to deal with that mess.
Also, the door to the bathroom is essentially a thin, rigid plastic curtain, and will do very little to muffle sounds or smells or anything like that. It’s marginal.
Amenities: It’s a wet bathroom setup but it has one very clever and important amenity:
A fold-down sink, over the toilet! Very clever and well-executed. The drain system is especially clever, too.
Emergency Use Viability: I’d say adequate, save for the door thinness. But, could be far worse.
Class C
This class has a lot more room for bathroom setups, and as such layouts and designs can vary wildly. Here are a couple randomly selected samples:
In this class we start to see more luxurious, “real”-seeming bathroom designs. Above we see a common “corner” orientation of the bathroom, and below we see a more “rectangular” bathroom layout:
While the layouts vary, the general amount of space and bathroom quality is fairly consistent, so this evaluation should cover the whole class:
Physical Comfort: Quite good! These bathrooms tend to have just enough space to allow for ease of sitting, moving, and performing cleaning duties, all while being small enough to make sense in the context of the overall vehicle and being fairly cozy, too. Decor ups a level here, and there are some attractive-looking materials and designs. There are some cheesy ones, too, of course, but generally these look quite good.
Emotional Comfort/Security: These Class Cs may be the sweet spot for this; windows, if present, tend not to be in unsettling locations, door thickness and distance from the toilet is more reassuring, and the overall normal-bathroom feel is very effective for pooping comfort. Again, the size is important, as it’s just big enough to move around comfortably and small enough to feel like a safe cocoon for private pooping.
Amenities: What, in addition to the toilet, is available? Is there a sink inside the bathroom, or do you need to exit to use one? If it is a wet bathroom, how much does the toilet area affect the use of the shower, and vice-versa?
Emergency Use Viability: Definitely. This would be a welcome refuge in a time of a shitastrophe.
Diesel/Gas Pusher Motorhome
These are, of course, the most luxurious and opulent of all the motorhomes. These are like those band tour bus kinds of things, and feel absurdly decadent. I mean, look at this:
All that shiny marble and brass and chrome? It feels like a Miami Beach cosmetic dentist’s office in there. This one actually had two bathrooms! Look, here’s one:
Damn, there’s even a seat in that shower! I don’t even have that in my house, unless I drag in a folding chair, which I was made to promise to quit doing. The other one was part of a larger en suite bathroom/dressing room connected to the bedroom:
Okay, let’s evaluate:
Physical Comfort: Of course, this is at essentially near-conventional home bathroom levels of comfort. The stability and substantiality of the toilet itself I suppose isn’t up to a non-mobile toilet, but that’s nitpicking, because this is a toilet you can use at a mile-a-minute.
Emotional Comfort/Security: Okay, here’s where it gets interesting: I think these are actually a bit less emotionally secure than the Class C bathrooms, because of their larger space and how the sheer size of the whole vehicle causes motion when people enter or exit. There may be ways to mitigate this rocking motion – and I’m almost certain there must be – but while I was testing in the bathroom you see above, I did feel somewhat … exposed. The cozy security of the Class C was gone here. The experience was good, but if I’m completely honest, I’d prefer to take an involved, complex shit in a Class C.
Amenities: Everything. Whatever you need. These are for high-rollers. Oh, though I have yet to see a bidet on one of these. That feels like a huge oversight. What are we waiting for? I want a bidet!
Emergency Use Viability: Excellent. No notes.
I hope this helps! Mobile pooping is a growing area of interest to people, and it’s something everyone – no matter who you are, from an Empress to your deadbeat cousin – can appreciate. I know a lot of society is invested in pushing the bowel-related side of human life to the hidden backrooms of our experience, but when it comes to motorhomes and RVs, it’s a crucial factor, and must be confronted with open eyes and minds.
I hope you have meaningful poops, everyone.
Thor rep: Who should we invite to the RV show from The Autopian? Mercedes Streeter?
Thor Daddy: No no NO! She keeps taking pictures of our rusty frames and misaligned trim. Who else do they have?
Thor rep: Jason Torchinsky? I’ll warn you boss, he tends to be a little… eccentric.
Thor Daddy: Just sent the invite. I’m sure he’ll write something acceptable. It’s not like he’s going to try to turn our show into a farce like she would, right?
Thor rep: Well…
Did you forget to replace the template for Class C amenities section? I demand this information is made available to the general public.
Also, agreed that an ability to take a bathroom break on the go is the ultimate luxury
Having lived through chemotherapy and all of the enjoyable effects that had on my bottom system, the proximity of bathrooms at any given moment and my comfort level with them at all times has become more important. This is the information the world needs.
> gas pusher
Very informative article. I read it earlier but waited to comment until I was in/on the proper venue. Kohler that is.
The unacceptable bathrooms in boats are the ones that share toilet and shower space. Psychologically unacceptable to me no matter how recently everything was cleaned. The boats they come in aren’t cheap and I’d rather just go without it and get a cheaper boat to boot. Next down is the cassette. F’n foul. That chemical stuff can splash up like a dye pack hiding in stolen bank money and they need to be removed and cleaned out. Oh, yeah, here’s my glamorous boat/RV life carrying out my briefcase full of turds, though an actual briefcase like that might make a fun MacGuffin in a Pulp Fiction sequel. I’d rather just keep a 5-gallon bucket and some garbage bags on board (for emergency purposes only). For an RV, I’d rather rely on public places or a trusty shovel in the woods.
Full disclosure: I got a fancy TOTO bidet toilet for a Christmas present fortuitously just before Covid when everyone was hoarding toilet paper and I am thoroughly spoiled now. That said, all those opinions on vehicle toilets predate receiving my Superbowl.
“splash up like a dye pack hiding in stolen bank money” had me rolling on the floor. COTD
Ah, someone else that I assume has faced the consequences of a dive bombing attack on a chemical toilet.
Gotta admit I’m also spoiled for my bidet seat. We’ve only got one of them, but I’ll walk all the way across the house just to use it.
Wow the whole distance of the trailer? You are spoiled. JK
I just walked all the way downstairs and across the house at 2:30 AM to use mine, when there’s a conventional crapper less than 10 yards from my bed! It’s worth the trip, every time.
I don’t mind if I am the sole poopinater. And in case of anal leakage or explosive diarrhea a handheld shower head beats a bidet.
Sometimes you have to think out of the box
Mine’s adjustable for position and force (and temp) and I’ve never needed anything more. Another thing I forgot that’s separate from this detail is the toilet itself—mine could flush the Yamato’s main gun ammo, which from someone who used to have to find sticks in the yard when he was a kid to assist with clogs, is also extremely valuable.
I noticed that In Singapore in particular, the public facilities often had a “bum gun” on the wall, next to the throne (or poop pan for those limber of leg and stable in a squat).

A quality shitter is worth it’s weight in gold. In the future I very well may end up living in a trailer, and I’ll have a quality toilet (probably stainless), a quality shower, and a quality 7ft long bathtub.
The Class A and C both have vent fans in the ceiling, don’t they? I know the class A do for sure. The fan will mitigate any nasty odors and maybe even cover some of the sounds? As far as the rocking, when parked the A and C will have jacks to level the coach and stop any motion.
Our B van has a separate fan for the head. There is an actual “door” with two hinging halves. It’s a pain to use though. We have blackout magnetic covers for the rear windows.
In my limited experience, the cheap fan may well cover the noise, but do little to mitigate the transmission of odors. The good fan that moves the air, is not too noisy.
There was one thing I was hoping for, the one thing that we’re all wondering but don’t want to ask.
Whats the MaP rating of these toilets?
Since the burrito science experiment didn’t work out, you could replicate it with a box of golf balls.
Just say “look!!! A 24 hour Walmart!” And everyone will turn for long enough for you to get the box of potential authority-calling racket on to the RV.
Personally, I want to see if there’s an RV with a 1000 MaP toilet.
No way we need a Jason and David spend 48 hours in an RV Toilet eating Mexican food while The rest of the team competes for the one raise available for the best lap time.
RV toilets are basically a poop chute direct to the holding tank w/ a swinging gate at the top (to hold water and effluvium) and a source of water to rinse the bowl. If you clog that puppy, eat more fiber and drink more liquids.
As a result of reading Mercedes’ RV articles (horror stories?) I actually thought this would be a Sheryl guest post… though a Torch byline also makes sense to me.
This is it. The one article that made my subscription worth it.
I never understood why RV manufacturers don’t just do a 1 piece bathroom like cruise ships.
This article is informative, hilarious, and a little crude. It nearly perfectly sums up the ethos here, and why we love it.
If this story isn’t in the Autopian Hall of Fame then we need to start one just for it.
I have a feeling Thor won’t be inviting either of us next year. xD
All I read was that you & Jason have a year to craft exceptional fake identities & hilarious disguises. Tell ’em you write for Jalopian Auto Picnic or another well-regarded, entirely fictional site.
Let’s start a fake mustache fund
Okay, since nobody’s said it – #1, this is a shitty review.
#2, it’s the scoop on poop. Pooparama. Poopalooza.
Sorry. I’ll quit now.
user name checks out.
You forgot about the most important bathroom amenity if you are traveling with others. That’s the exhaust fan. In a small space, if that isn’t doing the job, it’s a rough time for everyone.
I hate the toilet/bathroom in our trailer, but I put up with it. The space is too small and it’s right by the bed, but it beats leaving the camper in the middle of the night. It’s all about sacrifices and what you can live with in a smaller camper. We sacrificed the large bathroom for a great kitchen and living space in a 23′ trailer.
I recently did a bathroom renovation, and I purposely bought the loudest possible exhaust fan you can buy. Why? You know why.
Whisper quiet bathroom exhaust fans are not for me.
“Dedicated defecator” is a delightful turn of phrase and quite fun to say aloud, were one only provided with an appropriate occasion to deploy it.
And now attempting to spell it, I have a better understanding of the word “defecate” re: its meaning.
Torch, your work is truly the gift that keeps giving.
Screen name definitely checks out!
Have a Transit camper. Has a shower, never used it but great ski closet. Came with a Dometic toilet, new but I’ve never used. I do travel by myself. The windshield wiper fluid bottles are the best pee jugs. Even have a o-ring in the cap. The banning of plastic bags required that I buy 250 convenience store type from Amazon. That’s for #2. I’ve heard Marines use cling film.
Truckers use 1 quart Gatorade jugs.
Understandable. I have a cold spot under the floor by the sliding door to keep waste cool. once it got warmer… not quite as convenient. The bug juice bottle is kismet. Have to buy a lot cause big windshield and snow. But yeah, it’s not so hard. Black tanks are not on my horizon. Have a 5 (or 7) g jug under sink. small grey tank underneath shower. Could use Castile soap (knock off Dr. B) and it’d be great. but I’m not out long enough to need to use the shower in the field. demo mode only so far.
Yes but people are getting arrested in national parks for doing this.
Yeah, isn’t it crazy that the Free Republik of Kalifornia won’t allow the grocery store to give you a clean/virgin plastic bag to carry your groceries home in, to then your to like your garbage cans, but you can buy a box of hundreds of the same weight plastic bags to use for the same purpose.
Not really bathroom related… but my favorite type of RV waste disposal system is that one system that burns your poop as you drive.
The one that grinds up your poop in to a fecal Frappuccino and then injects that in to the hot exhaust gases under certain driving scenarios.
The Thetford Thermasan.
Unfortunately I doubt a modern rv would pass emissions after you passed emissions.
There are ones that seal the waste in plastic. Invented for crane operators. Like a seal a meal.
A crappuccino?
IIRC The Autopian has an article about that
I think it was our founders but for Jalopnik
I’ve seen a Thermosan write up within past 6 months so if it wasn’t The Autopian it was The Drive

I have not even read the article, but the headline speaks to my soul. As a committed pooper as well as someone who is kind of tall and wide I have issues with lots of restrooms that are not permanent fixtures. I will now go read this masterpiece and submit it for Pulitzer Prize consideration.
Seconded. This is true reporting. Important need to know information. Unfortunately rv manufacturers won’t let Torch do his in depth scientific testing. Do you hear me, Thor Industries? Let the man poop!
Wow, a lotta good poop, here.
Nah it’s just full of shitaki mushrooms
Because of the limited volume therein, everything in a van-based RV needs to serve two or more purposes. Hence:
And so on.
“There may be ways to mitigate this rocking motion – and I’m almost certain there must be…”
That’s why one must deploy the jacks before extending the slides – So that the weight is off the tires/suspension and the coach is stabilized regardless of interior movement.
The Newmar DutchStar that my folks lived in for 20 years was a great coach – except the midship bathroom was split – toilet and sink on the left, shower on the right – and the doors were paper thin, so that wherever you were in the coach, you could hear what was happening in the bathroom.
I would have had a difficult time with that.
Maybe this is why Bluetooth was really invented?
This is the reviews we need on campers. Mercedes on quality, Torch on poop. Most important details, honestly.
When you have windows, even tinted windows with a curtain on RV bathrooms, you get to give the whole campground a show when it’s dark and you have the lights on. This is kind of fun and sexy when you’re in a private place and your partner is showering.
It is far less sexy (but hilarious) when your low fiber buddy clogs your toilet at deer camp and everyone gets to watch his silhouette desperately fight to get his log of iron into small enough pieces to flush.
And I now have coffee in my sinuses
Junk’s comment needed a reader warning — a sort of spoiler alert.
He needed the patented reddit poop knife.
Well, I now regret making the Google search that made sense of your comment.
Aren’t the windows usually above your head? Much better than the shower in my Houston house that had a bay window in the shower from knees to above your head. With clear glass windows. Granted the neighbors got the worst of that deal
