We used the truck wash. On the plus side, they certainly spend a lot of time working on your RV so a thorough job was done. The price was $57.00 for a standard wash (no extras) seems high (Blue Beacon was $45.00) but a good job done overall. (Price on length, we were 38')
Didn't give full stars as the wait is horrendous, plan on spending the best part of an afternoon from waiting to washing.
