Enthusiast III
We have gone back to using the PETT system with the tent. I originally had that for my Jeep outings as it folds down nicely. When I built my truck camper I put a portable chem toilet in which can be used anywhere as well. My issue with the chem toilet is, when you go to altitude, it pressurizes! I have not had an issue with the black tank leaking as it is sealed up well...but the fresh water side pushes water out into the bowl and then obviously ends up all over the place. Additionally, with the wag bags from the PETT system, those can be thrown into your trash carrier outside of the vehicle (Trasharoo or other).
