I have a pair of 45 watt panels that are about the same size as the larger ones that you described.
I installed a pair of 120 watt panels back in 1999, and they cost $429! Now you can buy a 120 watt for about $175 each. SunElec.com
As long as they are working, I would leave them up there. They will keep the battery full while in storage, yet when camping, the CO, Propane detectors and refrigerator combined will use about 35 amp hours daily, or about what all three panels will produce.
So you will need to shut off the propane detector and refrigerator while in storage to keep the battery full.
There are several posts on how people have changed to LED lights if you are interested. I used some LED panels with 24 each 5050 LEDs on one panel. It is fairly bright, and draws only about 1/4 amp each.
Have fun camping!
