Solar panels on the roof would keep your house batteries charged in storage and recharge your batteries when camping. General rule is 1 solar watt for each battery amp hour. How many battery amp hours do you have? Generally runnng wire from the panels to the controller and then to the batteries is easy.
If they are fully charged when you put your RV in storage, you don't need anywhere near 1 solar watt per amp hour. If all you are doing is maintaining the full charge, 30 watts will do the job.
The first winter I just used my battery disconnect switch and they went from 100% down to 50% in 3 months - and they were brand new, good batteries.
