Roof mount Solar

When installing a roof mount system on a RV, do you try and secure the mount brackets into studs, or just thru the roof sheeting? The Renogy panels my son in law bought, came with some 2 1/2" wood screws, I'm thinking those are way too long if you arent hitting studs. Somewhere here, I think IO read they use particle board, but its more likely to be OSB or plywood, right?

Thanks for any help!

Short wood screws work best. 1 1/2" is good enough. Get a tube of Dicor self leveling.

Set the panel where it's going to be. Put one screw in one bracket about 1/2 way in. Repeat for all brackets. Now starting at any bracket take out the screw and squeeze a good dose of Dicor over the hole and where the other screw will go. Now install both screws secure.

Repeat this process for each bracket. Once done go back with the Dicor and completely cover the brackets. This is how we do it and haven't had a single comeback for a leak.

Yup! If the refer isn't on a slide, we love to run the leads from the panel down through that opening. We drill through the side of the vent base so we don't disturb the screen and then just seal it with silicone.

How about if the fridge is on a slide? Where is your next "go to" spot? This is my next project as well.

After you run the leads down the refer vent, do you then drill a hole to get into the under belly to route the leads up to the battery compartment? That is where I plan to mount my controller.

I recently had a solar panel installed on my Fuzion 342 which has the fridge in the slide. We ran the wires down one of the tank vents.

That's one option if there is room. We try that first and if there isn't we use a plate designed for the roof and drill a hole from the inside after pulling a wall panel.

My fridge is in the slide. Can you elaborate a little more on the plate designed for the roof? Got a link to purchase it?

What about using a tank vent; how do you get the wires out of the vent pipe at the bottom? Not sure I understand this.

Thanks
