I don't think that comparative cubic footage compressor RV refrigerators use less total energy than absorption RV refrigerators.
Compressor refrigs use less electrical energy, but of course absorption refrigs get the bulk of their energy from propane. So far, I prefer the all-weather, any season, any time of day, any location energy that is sourced from propane. This is especially my preference since propane is required on most drycamping RVs for other reasons, anyway.
Now ... if only I could afford to get my RV storage battery recharge energy from an on-board 24/7 propane powered fuel cell ...
