There is another option I suppose you could put fridge on casters and wheel it in and out of a space, but it doesn't make it easy to use.
btw, we had a large top opening thermo electric fridge in old van, it was quite efficient, but we find the present front opening door much better in use.

Better insulation will improve the performance of any fridge or freezer. Many liveaboard yachties build their own fridges with very serious insulation to reduce the power input. Reducing the duuty cycle down to 20% or less is possible compared to the 33% for ready made Dometic units. They all use compressor kits which are supplied by the likes of Dometic with 12 volt compressors. Not cheap but efficient and outperform any off the shelf unit. Whilst this is really not an option for factory built vans for self build it must be a real option. In hot climates absorption fridges need good ventilation but are hamstrung by the reality they can only cool to 30 degrees below ambient.
Edited to add some idea of the kits available. Most of the parts have self sealing connectors which means no nasty problems with refrigerant gas a much easier DIY solution

I was researching the same problem here are 2 great videos which may help the decision and save money etc.
the presenter is obviously attempting to promote an inventor but I do not think it interferes with the results.
Fridge Comparison Energy Consumption test with multiple fridge types in the leisure industry
230V Fridge comparison test versus a 12V compressor fridge cost / benefit analysis
Irrefutable evidence again by how they work compressor units are more effective. that is no slur on absorption cycle fridges and in the main serve well
Compressor fridge works great for us, never seems to pull much power although only been in the uk this year with it, saying that we have had some 30 degree days although not many.
I think a lot will depend on what you have unless starting out from scratch as the costs of either are high. Ignore the horror stories you read about compressor fridges though they arenít true.

Said by HD .... "Yes, a compressor fridge is far more efficient. But the power supply is far less efficient. 1KG of propane has 13KWh of power (plus the weight of the tank, of course). A battery with that much power storage capacity would weigh around 300KG."
But if "a compressor fridge is far more efficient" you wouldn't need "that much power storage capacity" would you?

I just read this long thread. Ignoring the tech which we may not understand, there are some quietly saying my compressor fridge works fine and others saying my 3 way fridge works but..... That is also my experience.
Solar panels allow you to suck energy out of the environment most of the year, at a rate plenty high enough to run an efficient fridge, so i run my fridge with only one 85 amp hour battery. The comparative weight of gas to batteries is not relevant. I bet hairy dog has more batteries than me?
My Dometic 3 way is sensitive to the mains voltage, it won't work below 200V
