The first thing I would look at is the roof. Many rvs that stay in campgrounds for extended periods do not get the best of care (especially roofs). Was it parked under trees? Did the owner take good care of roof, and slide roofs. Check every inch of caulk. If caulk is cracked or weathered, I would walk. That is a good indication of how it was cared for.
If you don't have experience looking at these things, bring someone who does . You are buying it as is, no warranty.
If you plan on Towing a lot, I would forget about the Towmax. I never trust Chinese ST tires under my investment. By the way, the manufacture date will be stamped on the tires.
Plan on at least replacing the tires, removing and hand packing the wheel bearings and inspect/adjust the brakes.
