Otherwise, if it is you simply do not like propane at all, swap the RV fridge for a home fridge conversion.. My current TT, we did a home fridge conversion, just one pair of 6V GC2 batteries powers everything we use including the fridge for 24hrs without the need for solar or a generator..

Gdetrailer,

Do you know the make and model of the fridge?

Haier 10 cu ft fridge, marketed as small apartment size, same manufacturer that makes Magic Chef and a few other well known brand names of that size.

I measured the current draw personally and average was right at 90W at 120V, compressor is marked as 1.1A draw.

Only downside to it is it is a frost free model so it does have a auto defrost cycle but that only happens once for 10 minutes for every 10 hrs of compressor operation. My timed tests gave average of 20-22 minutes compressor run per every hr from 50F all the way to 100F. Didn't bother testing below 50F as I am not a colder weather camper.

Paired that up with a Tripplite PV1250 MSW inverter which has a power save feature which puts the inverter into a deep low power sleep mode when it does not see a 120V AC load. That power save mode saves 24 Ahrs of battery capacity alone per 24hrs.

Since the fridge is pretty efficient the charge line from my vehicle is able to nearly support the fridge while driving unlike if I was attempting to run a absorbsion fridge off of 12V.
