Try getting a Ford dealer to work on a Class A or C. Many if not most will not accept them, many will do simple tasks that don’t require a lift. Mine was a current year model. I called Ford and every dealer they suggested would not work on it. I take mine to a truck service center.
Had a VW based Winnebago Rialta and could not get local VW dealerships to service it. Had to find a independent service company. I once asked my local Camping World what they told their customers to do about service. They recommended a small independent shop 20 miles away. Went there and quickly turned around.
