Yaz-that is a 44' coach, not an RV. Full sized tour bus. $1.3 million. Cost more than the guy's house!
Anyway, I washed it, waxed the front end (no time to wax the whole thing, but wanted the bugs to come off easier next time), sprayed down the engine, cleaned the windows and dressed the tires. Since I could let it air dry because of his water deionizer, the whole process took me a bit less than 4 hours. He paid me $150 + $25 tip. Works out to more than $40 an hour.
