I installed a booster pump when our in-tank pump started failing while passing through New Mexico on our way to the Grand Canyon. After getting towed into the campground where we had planned to spend the night, I ordered the pump and assorted hose, clamps, wiring, etc., from the local NAPA, and picked everything up the next morning. It took me about an hour to do the actual installation, and the coach has run fine ever since. My "ToDo" list this year includes replacing the in-tank pump though. I'm still deciding whether I want to drop the tank or do a through the floor installation.
