I have a little toilet in my truck to **** in if i have to. no water or anything like that and it just sits back in the sleeper area. no odor or anything like that, so when it goes to this i will just dump the pot on their feet,lol.
I bought it for 35 bucks in a rv supply store and it has been one of the better investments i have made. in a pinch you could drop a protein submariene but personally i think it is better for number one. a lot easier and cleaner than a bottle as well.
