Adding a Rear View Camera to 390
I bought a rear view camera (hard wire) to install on my 390 QSMB. Since its 41 ft I went with the hard wire install of wireless. I was wanting to install on back panel right below the window. Has anyone added anything to their back panel? Is it hollow or filled with foam? If I drill a hole to run wires I'm not sure how I would get the wire to the bottom or side if its foam filled. That way I can run wire underneath trailer to the front. Hoping to drill and hide wires without taking the back panel off or something crazy like that.
Thanks,
