Most RV buyers are unaware of what the issue is when they purchase the RESIDENTIAL fridge with all its space inside, and find that their batteries and TV can not keep up with the battery drain caused by the fridge. I attached a link to another post here that we dig into the problem (45Amp drain) and the fix that is working perfectly. The fridge type was a Frigidaire, but the same issue and fix can be done to any residential fridge.
Bare minimum, I personally would go with the TRUE deep cycle 6 volt batteries, will need 4 to ensure enough power, based on the findings.
Best solution, 4 true deep cycle batteries and 500 watts of SOLAR power with MPPT SOLAR Charge controller (will add about 40 Amps, with sun). This will cover your travels and keep the batteries topped off. This fix is a "MUST" for anyone that dry-camps or spends a night between CG's. I have 2 Trojan T-145 6 volt batteries (260Ah), and for 5 years they are working GREAT!
Adding the modification would be your best bet. Contact Klassic (member) for more information on his install.
