Holding Tank Emptying
I had discovered that my gas tank filled quicker and more completely when my RV was tipped to the right (see “filling the gas tank”). It wasn’t long after that I discovered the same was true for holding tank emptying. In my vehicle, tipping toward the left, with the nose slightly higher, I obtained better emptying. You can use either blocks for the wheels or leveling jacks.
So I use this technique if I want my tanks really empty. Most of the time, I don’t bother, especially when I know there is another dump station in my immediate future. But you might keep it in mind when preparing for those longer boondocks.
