I agree with Atom Ant. We had a double wide 4 door ref/freezer with ice maker for 9 years. 14 cu ft, the largest in the industry. Hated-every-minute-of-it!
FINALLY it died. Considered replacing the absorbtion fridge at $3,600 and opted for a 20 cu.ft. Samsung French door bottom freezer w/ice for $1,000.
What a vast improvement! Lights you can see with. Shelves you can clean. Thermometer right in the door header. It will "hold the cold" for a full day's traveling. Which is good enough for us. But if it wasn't I'd go for a generator before I'd go back to the absorbtion refrigerator.
Residential grade fridges are an entire category better than the gas/electric fridges. The plastic liner is a better grade of plastic. The insulation is thinner and better. Recovery on a compressor cooled fridge is much faster than an absorption fridge. The frost free feature for the freezer alone is worth it to make the switch. And they work in a greater ambient temperature range. When we had the old absorbtion fridge, when the outdoor temps got over 90 the food would warm up. And it never kept the ice cream solid. They're not only better, they're cheaper, unless you have to have alternative power source.
We've only been without shore power once in ten years. Once the truck had a problem and we were stuck at a gas station on a hot day. I got out an extension cord and plugged into the gas station for just enough juice for the fridge.
It may not be an option for you to find a unit with a residential type fridge. But it's not that hard to upgrade. Truthfully, it was more difficult trying to figure out how all of the plastic parts went back into the fridge than it was figuring out how to install the fridge. The ventilation panels are already in the side of the camper. Just don't block the air flow and everything's cool.
