Many motorhomes sit for long periods between use. 1-2 months is peanuts. For my gasser changing the oil once a year, having it inspected at a Chevy dealer costs a couple hundred. Washing several times a year, wipe on wipe of waxing once or twice, checking and inflating the tires, inspecting and washing the roof once, and cleaning and checking the outside components of the WH, refer, are about all it takes and these I do myself. You would want to take some care with the tires by covering them from uv/sun or spray them with a uv protectant.
