I only use a pressure washer on the underside of the fiver after I return from the beach. All that salt air from the sea breeze gets into everything.
I will do the frame, spare tire hanger, inside of the wheels, discs, Morryde IS, ...... basically anything under. i will not use it on the exterior

I'll say not even close on this one.
That water is coming out at a lot more than 70 mph, lol.
Think about it, a 2500psi + pressure washer. Pretty much any model with a gas engine will peel your skin off with a narrow angle tip, instantly.
But you could drive with your head out the window in the rain and it'll just sting. (Wear glasses if yur gonna try this, lol)

Unless using a high pressure Hotsy, pressure washers usually don't get all the residue off. Unless using a real good foam/soap, then maybe.
If you're good with getting it "80% clean" that's fine, but most of the time it takes a brush, sponge, something to get truly clean.
Household Pressure washer is good for getting the heavy dirt, mud, sand etc off to minimize scratching but usually not a 100% clean solution.

Ive ridden motorcycles in the rain. Doing 30....40...50mph those droplets hurt!! I also have a gas pressure washer and use it all the time. From 1 foot away the blast is mostly air and mist. Very gentle and doesnt hurt.
I think it comes down to the mass of the water droplets.

I have a pressure washer but have never used it on the rig - don't see why it's required and have always found the extendable RV washing brush sufficient.

We use an electric pressure washer but have never found out how to make the soap dispensers work which would be nice to have when washing an RV.
I have even used it on the roof which should be done first because the roof `crud' flows down the sides of the RV.

I used the Simoniz floor washer kit to clean my deck. Works great on the TT roof.

I would never use a pressure washer on my RV. RV's are prone to leaks as it is. A decent pressure washer can do some serious damage if directed at the wrong place. I have an electric one with only 1500 psi and if I am not careful on the house it can remove small bits of the mortar between the brick. Imagine what that can do to the gel coat, paint, decals and caulk on an RV. And I don't see the advantage. What's a pressure washer with a cone of a few feet from distance going to do that a long handle brush won't? And the idea that the psi from a pressure washer is even close to being comparable to driving in the rain is ridiculous. If you don't believe me, spray yourself in the face with your pressure washer - seriously, don't do that. Of course it all depends on the distance your using it. 5 feet away it probably wouldn't matter. Within 2 feet I'd say you are asking for trouble. I use a long handle soft brush and a regular hose.

If you are too close the pressure washer will definitely do damage. I think a full powered stream would cut right through a fiberglass panel. If you move far enough back to be safe, you might as well just use a garden hose with a good nozzle.
