Ok black and gray are empty but if we take a few weekend trips and use the toile and shower etc...how full should we have the tanks before dumping ? I know you do black first then gray,,,but do you r...
I always dump before I travel. Even If it has only been one night I fill the black tank so it is about 3/4 full before I dump.
The waste tanks have no support in the middle and if they are partially or even full the bottom of the tank flexes and will cause the tank bottom to crack.
