Stan,
a couple of months ago I won one of those in a photo comp in a 4wd magazine. During xmas used it as a beer fridge .On 240v not too bad - flat chat it stayed on about -3 degrees during summer days inside house and overnight went to zero. I always refilled it with cold replacements. Used it in car numerous times- takes a fair while to cool down (2hrs) and very heavy on second battery as most 3 way fridges are. Haven't tried the gas yet but in my opinion fairly useless as a mobile 12v fridge if thats your intended use for it's power use and only goes up to 25 degrees below ambient temp.

Stan,

problem with 3-ways as ahs been siad is that on electricity the chew the juice. This is becuase they use Thermo-conductivity rather then a compressor to cool things down. Gas is good if your likely to stay in one spot for a while as they are very effiecient but obviously you can't use gas while you driving. Another thing is that 3 way fridges are not as effiecient on space as your average 12/24/240v comprssor fridge; ie: you get less actual fridge space for the size of the unit.

My advice:
If your likely to be crusing around alot and have a decent dual battery setup go for a compressor fridge, but if you're staying then gas may be a good option.

Jim.
