rjd,
MAJOR BUMMER!!!!
Sorry to hear of your mis-hap and the resulting trip cancellation.
A suggestion on detailing: Try calling some of the larger RV parks or 'resorts' as they now bill themselves in your area. They usually have one or two mobile RV detailers on their park referral list.
We have them in the RV resorts that I service in FL. The guys are very good at what they do and usually have a large tank of treated rinse water so your trailer will dry spot free. Just be sure to tell them to go easy with the pressure washer rinse.
