Solar panel dealers can easily install on any trailer. Yes, will have to drill a hole in the roof, but we have had no problems on last two trailers and really nice to keep batteries fully charged all the time, and they last longer if not discharged frequently. I had dealer install our Bluesky controller on side of front closet closest to front batteries for less voltage loss. Use 10 gauge wire if possible from panel to controller and same from controller to batteries. 8 gauge even better between controller and batteries. We have two solar panels at 80 watts each and two 6v. trojan batteries and when boondocking at the Quartzsite rv show (AZ) the batteries are fully charged by 11am in the AZ sun!
