Guzzi,
This may help. Feedback from a 3rd party.

Hi Rexy,
I have just come back from Kinkuna National
Park, just South of
Bundaberg. I have a 40 L Engel Fridge/Freezer that I purchased 4 months ago. I have dual batteries and have hooked the fridge into the accessories battery. Some friends that we were
camping with had an Engel as
well, same capacity, but purchased it some 4 years ago. Still going strong but was draining batteries really fast. The other 4WD had dual batteries as
well and was setup identically.
I always take a Volt/Amp Meter with me and we measured the draw from both fridges. Our fridge drew 1.7 amps and the other fridge drew around 4.8 amps, quite a difference. The other fellow had 2 solar panels charging the battery but the best he could get out of the panels was around 6 volts.
We've since found out that Engel have improved the design of the fridges and that the insulation properties are different along with the compressor.
Drawing 1.7amps, I could leave the car without starting it for about 2 1/2 days. Ultimately, the perfect setup would be to have a glind shower that necessitates startup every night for heating
water for showers etc. Even with the solar panels and power management system, the batteries in the other car were down to 7 volts within 24 hours. Plus you have the cost of solar panels at approx. $600 a pop. My thought would be to get an economical fridge that draws low amps that cools/freezes economically...
