95 Fleetwood Bounder

I'm looking at a 95 Fleetwood Bounder That has sat for 10 years in the seller's driveway I'm assuming that the fridge, ac unit, tires will all have to be junked.Is that safe to assume?
It is in good shape and only has 36K on it Can I just try and start the generator to confirm that those items aren't working. Is there any way to plug into the 30amp service from a portable source?

I'll probably have lots more questions but appreciate any help 0n these basics.
Thanks Much

Mark
