We have a new trailer we picked up last spring, has a 12v fridge which compared to the gas/electric absorption ones I’ve had in the past is a nice change I really am pleased with. The trailer came with a 100w poly solar panel, 10 amp PMW charge controller, then I set it up with 2 6v GC2 lead acid batteries.
In a 4 night dry camping trip last June it did well, the campsite was in full sun after 10am. I didn’t need to pull out the generator during the trip to recharge but would have had we planned to stay longer.
It showed me for a shaded site or overcast days it needs more of its array on the roof and/or a portable unit. I’ll also be changing the charge controller to a MPPT.
One recommendation I’d have is to install a good battery monitor to keep an eye on your batteries. I went with a Victron BMV712 which provides some good info on what’s going in and out as well as a quick look at the SOC
