Hi David, Mike and I (for now) have a little different approach to supplying power for our compressor refrigerators. Mike has 240 watts of solar and a Zamp 160 watt portable suit case set up and his house batteries. We both have auto inter connections with our truck electrical system to keep the house batteries charged.
Where I difference in that I have a small generator, only 80 watts of solar and a huge 4D Interstate battery besides my normal house battery and a by-pass on my electrical system to my truck.
Something else to do is to upgrade your charge wiring from your truck to your camper.
