If the coach has been stored outside in the elements, make sure the roof and all roof caulking around vents, antenna, fridge venting, rear ladder mount points, and any antenna, is in good shape. Telltale signs of a leak, are musty smell inside the coach. In addition, make sure the antenna booster works, all plumbing fixtures operate as designed, and check all waste lines and sewer gate valves for proper open and closing and no leaks. Ensure all gas appliances work properly, and propane, heat, CO, and smoke detectors are working. Run the generator, and exercise the transfer switch. Even check the windshield wipers, and sprayers. The windshield wipers on a coach can be up to 75.00 bucks each side. The engine and tranny should be fine, just give the coach a good run, up to highway speeds, and give the brakes a good hard stop, too. Most importantly, check the tires. With as few miles as this coach has, the rubber is probably original, and way too old for safe traveling. Any cracks would indicate deterioration. Also, all tires have a date of manufacture stamped in code on the sidewall. Good luck
