I want to install a back up camera on our 22MLSWE. It has the pre wire but not the Furrion mounting bracket. It’s just a round cap holding the wires on the back side.
I’m going to have to drill holes in the back panel to mount it. What type of screws should I use? Sheet metal? And should I use any type of anchor, like the plastic ones? Or just screw into the wall?
I know to use clear silicone around the bracket and all holes. :-)

Thanks.
