How do you wash and wax these big beasts? I have always washed and waxed our campers at least once a year. We have never had anything near this size before. 36 ft long and 12 ft high.
I have a cost effective and labor free solution to rubbing and waxing: I just convince myself the oxidation is really patina and adds to the character of the trailer. Self delusion is sometimes very practical.
I do wash it before every trip with a bucket and pole brush, takes about 45 minutes.
