I assume you have a residential fridge. The solar systems are really new to dealers and they are not in most cases that knowledgeable. A residential fridge (while it’s running) is about 7 amps on 120v. That corresponds to 70 amps/hr on battery. Now, the average daily runtime is about 4 hrs/day. That’s 280 amps. Our rig, with nothing on but parasitic loads uses about 10 amps/hr. With our fridge on propane, we usually consume about 150 amps over night. With a residential fridge, you will be over that. As a side note, if you don’t have a DC to DC charge system, you will only get about 5 amps/hr from your truck. If you have factory solar, you can join the Factory Solar Flex group on Facebook. Best of luck. We also had battery issues our first trip. It’s a learning curve but lots of knowledgeable people around.
