Late 80's and early-mid 90's Fleetwoods had a tendency to suffer delamination of the fiberglass sidewalls due to a less-than-superior gluing process, so look at the skin closely for raised areas (sometimes called bubbles). Actually, it is not a huge problem if it is glue failure rather than a leak that caused it to de-bond - we had a 96 Southwind that with a couple such spots and never bothered to repair them. You had to look close to see them and the luan plywood backing was solid, so not big deal.
Southwinds and Paces (they are all but identical except for color schemes and upholstery) of that vintage came on both Ford F53 and Chevrolet P30 chassis. Personally I favor the Ford, but the Chevy is probably OK if you replace the crappy steering bell crank with a Henderson Supersteer unit. The Chevy also tended to overheat and crack heads or exhaust manifolds, but some of the Fords did that as well. It was not an unusual problem in that vintage of RV, regardless of who built the body on the chassis.
Engines and transmissions got better in the mid-90's and I would opt for a 95-96 over the earlier ones, even though you don't plan to travel much. But if you aren't traveling much, why buy a motorhome at all? A trailer would make more sense if you park it most of the year. You don't even need a tow vehicle - have a professionally moved when you want it relocated. Leaving a motorized chassis to set for months at a time is a maintenance headache - the simplicity of a trailer is much preferred in that scenario.
