Thinking about a Truck Fridge.
I found a 4.4 cu ft model real close to the dimensions of my gas fridge. The specs say 24 watts per hour. That is 2 amps per hour? If so that is right in the ball park with my Engel 45 which used...

I've never had an issue with my propane fridge staying cold other than their tendecy to blow out which I remedied with a baffle. Maybe your fridge is defective, you need additional insualation, or it is way out of level. I believe propane is by far the most efficient way to cool.
Lots of info on the Internet detailing refrigerator efficiency. Modern compressor vs absorbtion fridge, there is no contest.
If you don't know,I'll give you a hint. It's the one used by 100% of homes in North America.

Nobody is arguing that residential compressor fridges on 115VAC are not efficient. It takes a really long extension cord though to drive around while remaining plugged into 115VAC.
Generators running on gas are not efficient like home AC power. AGM batteries providing 12V to the fridge are not efficient like home AC power (there is power lost when charging the battery, power lost while the battery just sits there, and power lost due to internal resistance when draining the battery).
Solar is efficient, but not so much when you are parked in the woods, or it is raining for 2 weeks. Also there are up front costs in purchasing the solar and the AGM batteries (about $200 each, right?) A AGM battery is only going to last 4 or 5 years under heavy use, so there are replacement costs there too.
It would be much much cheaper for RV manufacturers to just toss in a residential $200 AC compressor fridge instead of a propane refrigerator. Do you really think they would spend money on something that is poorer performance but costs their bottom line a lot more? Not likely.
