Dometic 75DZ Update: Had it running for 11 days now, filling it up with some of the bulk food items I've been busy in the kitchen with. Just a few items, a few of which I put in thawed, to see how the unit would perform in freezing... I must say, I'm very pleased with this mobile fridge/freezer. Been holding steady at 5 degrees since the beginning. Not as cheap s the ICECO, which I'm sure is a great unit, just noting my Dometic appears to have been a wise and prudent purchase. Very happy!
