The answer to your question is, not really. It could be done, but you would have to strip out all the workings and fab in the complete refrigeration unit from an absorption refrigerator. The absorption unit is totally different and as mentioned before, does not use a compressor. It uses ammonia as a refrigerant and boils the ammonia using either a gas flame or heating coil (which makes it very inefficient for use on electricity).
In my experience with absorption refrigerators, they use an unbelievable amount of gas, especially here in the hot South. I have developed a preference for standard compressor-type refrigerators. In fact, although I have a Norcold AC/DC refrigerator, it is quite loud on DC and offers no protection against battery depletion; so I think the best arrangement is a 110-only fridge and a good inverter. The money you save by forgoing an expensive specialty RV fridge can be spent on more batteries, solar panels, or both.
