We are on the road all the time, we have no residence. Most RV parks will not let you wash your RV. I have used truck stops that charge from 75 to 125 dollars and do a terrible job. What do most do?
Drive really fast in a light hail storm. Really I'm with you on this. Even in the sites that say NO CLEANING I've been known to get the simple green and a ladder and clean the front cap at least before the bug carcasses putrefy on the fiver. I like the idea of a mobile washer unit guy/gal coming around and cleaning for a fee. It isn't cheap and if I hitting the road the next day I would pass but if I'm staying a while it is a good deal.
