The thermal absorption type (ammonia solution) used in RV's are very finicky. If the RV isn't parked close to level, the fluids in the absorption system can get in the wrong place so it no longer cools. I had one that didn't work (Dometic), so left it upside down for 6 months and other ideas that supposedly could restore it, but no luck. Since a new cooling assembly cost $700 or a Chinese fridge $500, I kicked it to the curb (rebuilder took it via "free stuff" cl ad). I put in a small 120 VAC "dorm fridge" which fit perfect ($180) and added 1000 W inverter ($120) to run off 12 VDC trailer battery or vehicle when no shore power, which is how RV's come today. Then fixed all camper trailer problems by selling it since wifey refused to use it and needed the parking space for my too-many cars. Haven't given up on the old Mopars, though wifey doesn't appreciate either. Offload wifey? No, since she hasn't yet fussed about my fishing (a country song).
