I have a ZEROXCLUB 7″ wireless backup camera that I want to mount to the back of my 32′ 5th wheel. I do not want to drill holes into the fiberglass or roof EPDM. Do you see an issue with mounting it to the ladder? I do not use the ladder to access the roof and it seems pretty rigid. —Rik, 2012 Forest River Sterling 5th wheel
The only issue I can see is that most ladders vibrate going down the road. Even though it may seem sturdy or rigid, as you state, try climbing up it and see how it moves. Even though you won’t have that much weight on it, I believe it will still vibrate.
According to the photos I can find on the web, the ladder looks like it goes up over the roof and mounts to the roof top. There’s a post attaching the ladder to the back wall at the middle, and it curves at the bottom and attaches to the back wall again. There is very little side-to-side support with this type of design, and the slightest vibration will give you an earthquake-like screen. Here is a similar mount. As you can see, the top rails curve up and attach to the roof.
Mounting a backup camera on the RV
I would not be afraid to mount a small camera on the back wall or roof, as the ladder is already mounted that way. Plus, you are only going to put in two small screws, in most cases. Use butyl tape under the base, attach it to the roof or sidewall, then cover the screws and around the base with the appropriate sealant for either fiberglass or rubber membrane.
If you are attaching it to the roof, the base will most likely be horizontal and you would want to use a self leveling sealant. If you install it to the back wall, you will want to use a non-leveling sealant so it stays put and doesn’t run down the side.

How do I mount and seal security cameras on roof of RV?
I want to mount four security cameras on the roof of the RV. Should I be concerned with drilling and sealing holes in the rooftop if I put Dicor over all the mounting fasteners? Should I find a stud or frame to drill into or …? Thanks. —Jerry, 2011 Thor Chateau 22B
