$10 a foot is a fair price….I've seen them for $8-$10-$12. Like some here I LIKE to Tip especially if the rig looks great. I paid $450 in florida for a wash, wax, detail, rims, tires, roof…these guys even polished my horns on the roof and took great pride in getting my marker lights all the way around. Since there where 4 of them I gave the lead person $50 extra and in front of the other workers told him they should all stop for lunch and a beer on the way home on me……they were thrilled.
Since I go to this park for 6-8 weeks every year I'm sure it will get me some mileage and a repeat great job next year.
