G'day Rosco, We have a Dometic 4601(185lt) 3 way fridge, as long as the fridge is installed properley ie enough ventilation, the right insulation around the fridge you should have no problems. We did a test on gas, 6 weeks on a 9kg. :thumbsup: I think it all depends on your preference, we liked the idea of less weight(less batteries) and electrics. No compressor noise. Our van runs 2 batteries 1 solar panel. The batteries only run the LED lights, TV and Radio Hope this helps. Mark & Bernadette :shades:
