What prompted you to sell your MH? Are you going to replace it with something else, or go without an RV?
I plan to keep mine (a twin to yours). The only problem I'm still having is an oil leak on the base plate of the air compressor. The bolts loosen up after a couple hundred miles, and it leaks enough oil to splatter my towed vehicle. I've replaced the gasket several times, replaced the lock washers, tried different kinds of gasket goop (silicone, #2 Permatex, #1 Permatex) all to no avail. I even tried orange Lock-tite, which is supposed to be stronger than blue but still removable with a wrench without applying heat. That proved to be worthless! Must be a vibration that loosens the bolts.
