X3 (or whatever) on Blue Beacon. I know you said you like to do it yourself but from time to time BB is a great option. Check with the campground when you check in. Some allow washing but most do not. If you just need to get the bugs off the front, most CG's will allow you to do a bucket wash and then rinse. I am not a fan of the dry wash options. I don't believe you can get real dirt off without damage when so little fluid is involved. If your coach is dusty it might be OK but I do not trust it to properly care for a nice paint job.
