I made the mistake of eating a pre-heated breakfast sandwich at the truck stop before making my delivery, when I arrived with load of chicken, the tyson warehouse was closed, I parked the truck and jumped out to find a place to relieve my upset stomach, it was an emergency in my eyes, I spotted a bridge and thought I could go under it, when I got closer I realized thats where 100's of homeless people had their tents, well, I didn't want to leave anything in their so called yard, so I ended up wedging myself between a pillar and fence. LOL so anyways, I had to hurry cuz I wasn't exactly the right color for the neighborHOOD. So anyways the moral of the story is, porta potty is beneficial and pre heated foods are not advisable especially the kind with egg in it.

To empty the toilet you would do as the RV's do. It has a hose that you hook up to a service center, rest areas and most truck stops have those services.
