Almost certainly Tires and Brakes. You might be able to run tires 8 years if you USED the coach. With that much standing, the oils have left the sidewalls and maybe more. I'd also be surprised if brake caliper pistons and slides aren't stuck. If the generator had gas in the carb, you'll need to replace it.
Re-seal the roof.
What oils in the tires? I've heard this claim a few times, but it makes no sense whatsoever; the rubber is made from oil (petroleum products), but it does not contain liquid oil. If it did, the tires would leave oily marks when the vehicle was parked on e.g. concrete for a long time, or when the tires were stored for a long time on a piece of wood or whatever, or when the tire was damaged and the rubber torn apart; yet these do not occur, or at least I've never encountered them
Using the vehicle would also tend to force the oil out of the sidewalls due to centrifugal force, wouldn't it?
Tires age because of time, UV light exposure, and ozone mainly. Certainly old tires should be replaced or inspected as appropriate for safety.
Per Tire Tech website
Don't store a vehicle with weight on its tires for extended periods of time. Long-term inactivity is more harmful to tires than weekly drives that flex the tires and help maintain oil dispersion within the rubber compounds.
