GMC made a motorhome that pumped sewage through its exhaust on purpose

There are systems that can do that too... blue ice from airplanes?
or DEF:
OMG
No processing whatsoever, you could look down and see your train zooming through the granite.
And to add one of those things you can't unsee once you learn about it(sort of the nautical equivalent of font kerning) the flag on a sailing ship should always be fluttering forward for the same reason, the problem is our intuition is built around motor vessels where the vehicle is faster than the wind and does flutter backwards. so it looks wrong and quite a few artists get this incorrect in modern paintings and video games.
A Finnish saying "Works like a train toilet" meaning something that works with utter reliability.
This is because old Finnish trains simply had a flap in the toilet to dump the shit out onto the tracks. However, if it broke, it would invariably break in the open position, meaning it still worked.

Ahead of the curve on DEF!
Of course not; these are not germs that are killed by a hot exhaust pipe.
Misleading. RVs have separate tanks for toilets or use chemical toilets. "Sewage" is water from shovers or washing dishes.
You sometimes still still a combined tank on modern units, usually smaller ones.
I don't know what you mean by "chemical toilets", I put digesting/deodorizing chemicals in my RV's black tank, does that make it a "chemical toilet"? Either way, the liquid I drain from the black tank is definitely what I would call "sewage".
Honestly, this thing doesn't sound like a bad idea at all. It would be interesting to see how it really affects tailpipe emissions with some modern testing (when it's working properly, of course).
Seriously the savings to the RVs for polluting the commons are probably pennies on the dollar for all the issues this could cause others on the roads and near them.
How so? It only releases liquid waste, not solid waste, and it's released into the exhaust stream that's 900F, at a rather low flow rate. Just guessing, I'd say the emissions from this device really don't sound harmful at all, whereas the emissions from the vehicle's engine itself (which probably lacks a catalytic converter since it was 1973) are quite awful. I'm also guessing that the emissions from this thing can't possibly be as bad as the emissions from all the diesel pickups today with their engines modified to "roll coal", which is rather common and completely unregulated.
Would you agree that's a bad thing? This is intentionally dumping waste in a diluted form; but right in front of the possibility of a sea of cars which happen to not be in a traffic jam (35+ mph IIRC?). Well maybe the motor-home is safely and slowing taking the curves on a narrow 2 lane highway with no real opportunity for passing with a bunch of cars backed up behind it, forced to endure the exhausts.
Of course, I'm with you - wouldn't want to be behind it either. That said, in the 1970s cars left a cloud enriched with lead so ...
Until you get the message on your dash "AdBlue tank low. Please urinate to start engine."
Edit: Many people do not collect their poop. Or leave it behind on fence wrapped in thin bag. And most just pick up like 70% and leave rest. And diarrhoea is just smeared thin all over the floor.
But by "excrements" I also mean urine. And small bits that fall from exposed dirty but-holes, like when dog sits down, and leaves brown marks on white seat.
Similarly, many public parks require that dogs be kept on a leash. However, here again dog owners don't think they need to follow rules, and let their dogs run loose. Reminding them of the rule is usually met with hostility, profanity, and physical threats.
More on topic diesel trucks and buses had the tail pipe coming out of the back. I remember carping at my mom for always stopping right behind buses. And she said, oh you're right.
Different world before the 1970's
What else did you imagine might happen? Motorhomes are designed to be parked in RV/trailer parks where there are sewage hookups. Without that, the number of possible outcomes is pretty limited.
with a cassette toilet, you can take out the cassette, roll it down the sidewalk to someplace with a conventional bathroom, and dump the cassette into the conventional bathroom's toilet; then flush. then you walk back to the rv. some people have tote bags for their cassettes to keep this subtle. this is needed a few times a month
blackwater tanks last a great deal longer, months, but at that point yeah you need to go somewhere with an rv dump station. better get the engine running by then. this is one reason blackwater-tank rvs are practically unknown many places
with a composting toilet, your dried poop and composting medium is just another trash bag to take out, about once or twice a week. if you've never used one, you'd assume it stinks, but generally it doesn't. (pee goes in a separate bottle, which you need to empty every day or two.) logistically this is a little bit more work (you have to get the composting medium from somewhere, and if you gather it in the forest, you need to make sure it isn't going to hatch ten thousand crickets to greet you the next time you have to poop) but it's a great deal less risky than having a bottle of raw sewage
Where do you think those squatters are going to dump that waste?
My question stands, why would someone expect a different outcome from the actual one?
They have no legal access to a toilet, so where do you think they are SUPPOSED to poop?
i haven't been in seattle this millennium, so i can't do more than guess what the mix is. over 95% of factory-built rvs in the usa have one or another of those systems, and something like 70% of diy rvs. diy rvs almost never have blackwater tanks, always either composting toilets, cassette toilets, or nothing
where will campers dump waste? it matters a lot which system we're talking about
composting-toilet waste, as i said, can easily go into the normal municipal solid-waste stream, same as disposable diapers, but with less smell and health hazard
cassette toilets can be easily emptied into any sewer-connected toilet. when i lived in the usa, most gas stations, supermarkets, and restaurants had toilets with sewer hookups; also highway rest stops and for-profit truck stops (flying j, love's, etc.) also, if you have any friends who have houses, even a single one, you can dump it into their toilet. or pay for a hot-sheets motel room once a week and use theirs
blackwater-tank systems, you're gonna have to drive to the koa kampground or a truck stop 2–4 times a year
