If your not a fan of the 303, then use 3M marine paste boat wax. Its about $24 a can but a can will do the exterior of any RV. We had great luck using it on dark-Flag Blue- hullsides when I was in the boat business. Most people used it once a year.

Thanks for the advice everyone! If we can get past the "full time RV financing", we'll be using these tips!!
What's the best thing to use on the RV exterior to preserve it from the sun's harsh rays?
