I don't pretend to be an expert. So with that said my son and I have pulled his gen and it isn't hard to do and then had stator out and replaced bearings and back together in just a couple hours with a minimum of tools and effort. Not knowing your MH and gen location maybe it would be worth a look at for you and your son. Parts can be purchased at several different web sites or stick and brick locations.
Believe me it would be much cheaper that way than finding a good used unit and then also how good is the unit you get. Just my 2 cents.
