I'm with you all the way on this one, Don. I am not comfortable with directing any stream of water directly at windows, doors, vents, or compartments. I think the sealing strips around all of them are very susceptible to water under pressure, even from a garden hose. Some opening like the little door for the shore line don't have any sealing material on them at all. Same for the outside vent for the stove. I spend a lot of time when hosing the trailer imitating the way rain runs down the sides of trailers so that I am not forcing any water into any where.
Several of the insulating/sealing strips around compartments and doors are beginning to pull loose and will have to be replaced this season. The adhesive breaks down over time, and some of the closed cell foam they use will shrink over time, pulling the strips away, especially in the corners. But our trailer is now 9 years old, and I expect that kind of thing to happen.
I think using a pressure washer just magnifies the potential for forcing water into places it does not belong.
