I have a 3500 Express. I've read of problems with the holding tank collapsing, due to the high suction during pump out. I have also read, if you open the toilet valve during pump out, it shall let plenty of air in the tank and keep it from collapsing. My thought is to stick a foam noodle float in the toilet to keep the valve open during pump out. Any thoughts if this would work.
