bolt locations
We have a 2014-built 19' with a roof-mounted 160-watt solar panel bolted to 2 aluminum U-channels that are presumably epoxied to the roof.
I looked at this today to see what is under the aluminum U-channels on the inside. In other words, where would drilling from the top through the channel penetrate. The only good reference is on the passenger side at the collar where the power wire enters --it is about 1/2" to the outside of the wood strip that supports the overhead cabinet. The passenger-side U-channel is about 3" inboard from that collar. Seems the cleanest solution is to bolt into that cabinet support wood. It provides a reinforced backing, wouldn't be visible, and wouldn't require peeling back ceiling material, plus it avoids the power feed wire that runs inside the overhead cabinet along the ceiling. Those holes would need to be fairly exact, however, and I don't know how well it lines up. I also don't know how precisely the aluminum channels are placed from trailer to trailer. If the U-channel doesn't line up with the cabinet mounting wood, it's possible to make a bracket that fits over the channel and bolt that into the wood.
I'm just hoping this is a clean retrofit with clear instructions on where to drill.
Again, this is the 160-watt panel, so the 90-watt panels may be different.
