Hi all, recently completed 20 day outback adventure - Oonadatta Track, NT - Uluru and all the sights - camper trailer in tow. I purchased the 48L kickass single zone, - fridge / freezer - this product was the envy of my travelling companions - with wifi (app) controls - monitoring the freezer, adjusting temperatures gives great peace of mind - all food remained frozen - I was able to provide ice throughout the journey - its robust, top quality kit - very efficient - no power issues at all for the 20 days and returned to adelaide with food still frozen solid and back into the freezer - great stuff
