I pull into a Blue Beacon every time the camper is needing to be washed. They have done a great job. Usually I let them wash, rinse, wax and put RainX on both truck and camper. Most of the time it's around $60. After they are complete you pull out an do a walk around with one of the guys and then your down the road.
