Installing Solar Panel without roof penetration
I added a 33watt solar panel to help keep the batteries topped-off. I mounted this without penetrating the roof system using stainless steel brackets bolted to the steel vent flanges. Note: plastic vent flanges aren't strong enough for mounting the solar panel.
See attached picture.

I've just had my 2nd solar panel fail because a wire inside the panel corroded and failed. I believe it might have been caused by water pooling on the panel and eventually penetrating the seal. Anyway, when I replace this one (under warranty. we'll see!) I'm thinking that a bead of clear silicone might be a good insurance against another similar problem. They were exposed to freezing and just a bit of moisture can raise the frame and allow more moisture in. FYI

Anyone consider epoxy? Advice
I'm thinking about mounting a couple of rails crosswise on one half of the roof that I could mount a solar panel to with some quick release "star" bolts/screws. I would then be able to remove when camped and place it on a portable mount where i want for optimal sunlight----so i can camp in some shade, maybe.
I know there is some good tape products out there for mounting (don't want to drill holes in roof) but i question how well they will work on the rough textured aluminum roof. However, WEST SYSTEMS makes a variety of great epoxy products and they have a "flex" product out the last couple of years which bond to metal and wood and plastic etc. I've used it to repair canoes and kayaks and am trying it on an older aluminum boat. I'm thinking i could use either aluminum or maybe wood for rails- like 1x2 or 2x2. I received an 18 watt panel and 7 watt charger as a gift and am anxious to use it.
Any thoughts or experience or disater stories to share?
Thanks Rick

Never tried epoxy to hold brackets down, I think it wouldn't hold up in the long term. There is alot of lifting pressure when towing the trailer down the freeway, add the flexing and temperture changes also. If you tryed it, use aluminum rails the length of the panel,maybe on all four sides. Never use wood.

How is roof attached?
Well- still, along these lines..........does anyone know how the aluminum roofs are attached and what they are attached to? Are they bonded to whatever is under them? What IS under them?

depending on the actual size of the solar panel, you could use aluminum angle and bolt it in between the skylight and bath vent using existing screw holes from each of these. this was done by a nother hi-lo forum member last summer and it looked great!

Solar Panel /caulk
I wouldn't use silicone caulk. It is a bear to remove. We have been using Lexell caulk which can be found at your local ACE hardwear store or on the internet. It costs $8.00 a tube and is well worth the cost. I always give credit where credit is due. Another forum member uses this in the HVAC work they do. We wouldn't use anything else on our HI Lo. Silicone caulk is almost a dirty word.

Get a 500# gorilla to sit on the panels while you're towing. Then, of course he'd have to get off while you're camped and, you'd probably have to feed him.
Maybe you could "smooth" out the roof and go with the suction cups?
