I would never do it again. When we bought our used MH we took it to a dealer and payed big bucks for them to go over everything - engine, brakes, transmission, generator etc. The didn't do anything we are pretty sure as the air filter on the generator was so clogged it was getting no air. We changed the filter and generator ran much better. Not sure if they changed the fluids they were supposed to have done. Only went to the dealer as RV was our first one. DH usually does everything on vehicles so he just started doing all himself.
