A reputably manufactured portable or composting toilet is acceptable, but you will need to be able to use it in your rig and cannot ask a host if you can empty it on their property.  You will need to make arrangements to do so after leaving. Bathroom tents are not acceptable on a host property.

However, just having a composting or portable toilet is not sufficient; your rig must also be completely self-contained. 

NO tents, mini-vans, cars, or trucks will be allowed to join as guests.  Even if your mini-van or car is fully self-contained, they are not allowed in the program.
