I'd heard about these foam canons and thought I'd get one for washing the RV. Works great on the Roadster too! They're about $20 and attach to your pressure washer- no, the force coming out isn't that strong, at least on my cheap-o washer, safe to use everywhere. It helps getting soap into those harder to reach places and sits there for a while. Same scientifically proven principal that says you should leave the dishes soaking overnight
You still have to put your elbow into it with a cloth if you haven't washed in a while, but I think it does a pretty good job of making the job a little easier.
I use a foam gun with my 4-wheeled GF's and am very happy with it; but my R3T gets the hand-wipe treatment. For the same reason I don't power wash engines. It would be my luck water and soap would get somewhere I didn't expect it to and cause problems. I'm probably overly cautious... but I can live with that. Have fun taking care of you baby!
