Well it is certainly possible. You guys assume there is a 3',4',5' vertical drop. of the sewer before connecting to the horizontal line, But there doesn't have to be. The sewers can be quite shallow with no vertical drop at all and the rat could simply run up the pie. Remember the line only needs to fall 1/4"/foot.
These are campgrounds we are talking about. I'm sure the sites are not always plumbed to code.
Furthermore consider that the sewers can flood/overflow and the critter could simply swim up the pipe or get washed up with the back flowing sewer water.
I have read stories of RV's flooding do to sewage back ups.
I have personally witnessed homes flooding do to sewage back ups.
Yes in those back ups toilet paper and #2 does come up and end up in basements. A critter could easily wash up or in with the backflow of water.
I have witnessed sewage flies in sewers and getting into homes and businesses so it's easy for me to see flies getting into a RV.
Rats are a bit more of a stretch but it is conceivable.
I believe rats do have access and live in the sewers from there it's not hard to imagine one crawling up or being washed up a pipe and into a waste tank.
The video mentions it is a rare occurrence. While I no first hand knowledge of a rat in a tank I do believe it is possible.
