One thing in the dumping department that I found really handy which unfortunately is not on my new coach is a macerator pump. When camping out at Chula Vista last March I didn't have enough sewer hose to reach the dump drain, as it was placed way in the back of the pad.
I did have a macerator and an extra garden type hose I didn't need. Hooked that puppy up, and was dumped in minutes! It even had an outlet on both sides of the bus, very cool. I wish my new bus had that. It was slick.
