What would you pay to have your 5th wheel washed & waxed

I use a pressure washer all the time, just don't use it with full power. That wouldn't be any different than a car wash. The only issue I've had is not being able to keep it from water spotting on the rinse until this year, purchased a water deionizer to run the rinse water through. I had asked a local cleaning outfit that cleans cars on car lots and they told me $100 to wash it and if I wanted a paint sealer put on then I'd be looking at around $700.
