We've never had an issue finding a campground that doesn't mind. Not every campground but enough that it's not an issue.
Also, it's common to see a large vehicle bay at car washes. I'm sure you could use that for under $10...that said, I'm not crazy about pressure washers on RVs. It's too easy to blast out caulk.
I won't use high pressure wash as it forces water into places it's not supposed to be and can destroy the sealant as you said. A bucket of soapy water and a RV wash brush from Wallyworld and I can wash the trailer in 30 minutes.
