we leave the fridge on with water and other refreshments in it. as above said. it's grate for working outside. you can take a brake in the RV with a cold one.
i have a inverter in my 31E and when i unplug from the house to excersize the generator, the inverter says about 300 watts. the only other 120v things on is the tvs in standby "phantom" power. so i would say 300 is 95% fridge.
BTW my fridge is a 6 cubic foot dometic.
