How about a friend with a good access and a large yard or driveway?? You spring for the pizza and beer and offer a few dollars toward their water bill. Definitely DO NOT use a pressure washer or let anyone else do it. CW does offer "spa service". Have no idea what the cost is, but surely just washing the outside and you handle the inside and do any waxing should be fairly reasonable. Thankful every day that we were able to build a large covered area for the ROO and now Rocky. Gets protection from the elements and, although it still gets dirty, not nearly as much as total outside storage.
