How does this happen, physically? Do fancy tour buses have a “dump poop” button that the driver can actuate while under way?
My motor home has a black tank with a dump valve, but to open it I have to be standing outside the back of the vehicle, open a big hatch to the wet bay, and pull a lever. This is not something that could happen while the vehicle is in motion.
Also it takes a few minutes for the tank to drain out — much longer than the time to drive across a bridge — and if I did it without the sewer hose attached it would mostly go out the hole for the sewer hose under the dump valve, but also I’m sure the side splatter would make an unholy disgusting mess inside the wet bay as well.
Assuming you wanted to do a deed like this with any normal motor home, I don’t see how you could.
Has anybody got more technical detail on how this dastardly deed was done?
