More advice/opinion: Roof AC units, furnaces, fridges, converter/chargers, house and starting batteries, and RV generators, fresh water pumps and awnings MAY start to require expensive repairs/replacements when 10 years old. Tires that are older than 5 years old by DOT date codes may not be safe to drive on if they have sidewall cracking regardless of tread depth or appearance. These potential cost items are common to all brands of motorhomes as the same brands of appliances are used in most all motorhomes. Get written estimates for any repairs/replacements needed from qualified sources before deciding to buy a used rig.
