Keep in mind the fridge was intended to run on 12v power only when the engine was running to conserve propane, that's why they installed the relay.   I'd rather get propane every three or four days than a new battery every few months!   Maybe if you covered the top with solar cells . . .

Some people wire the auxiliary battery in so that it will run the refrigerator when the engine is off.  They hope to get an extra day without using propane that way.  But it will drain the battery in a day or so.
