Gifted Class A

I have read and pondered and remained silent. However, unless you can do a very good trouble-shooting job on all systems (plumbing, electric, chassis and engine, etc.) I would be looking to unload this coach as soon as possible for as much as I could get. It it runs then maybe put on new tires and change all fluids, belts and hoses. Clean everything (headlights to engine and radiator) and put it up for sale. If there is obvious rot, water damage, rodent damage you are going to have to be willing to go all in or get out with a few bucks. The choice is yours but you have a huge project in front of you and I am not sure that what you received I would consider to be a gift.
Keep in touch and let us know what you do. I wish you the very best.
