I have the Iron Man cube in the 105 that was in Oz. When we arrived in Oz we were very kindly given a large quantity of good quality meat, so we ran the smaller compartment as a freezer and the larger one as a fridge. I can confirm that this fridge/freezer does have seperate temperature controls for each compartment. Running the freezer did consume a lot of power from the battery, even overnight; however we were in temps of 45C day and 30C at night! Once the meat was eaten we ran it as a twin fridge set up which has worked well ever since.
It's 4 years old now and is still working fine. I may have the 105 at Lincomb as a day visitor on the Saturday if you'd like a look to compare. I do hope to pop along to the AO show this weekend, again on Saturday, but I'm not sure if I'll have the truck with me.
Personally we don't have much of a call for a freezer when overlanding, a fridge, be it a large one in this case, does us perfectly and sees us go 5 days on our supplies. I wouldn't want to stock for a whole trip door to door, as part of the fun of overlanding is to embrace the foreign shopping experience. Restocking at the Marrakesh in door market was great fun.
I also think very highly of the Engel fridges, I bought a 35L in 2006 and added a two-zone to it in 2007. It has been used in numerous trucks and cars, as well as provided addition fridge capacity during Christmas periods. I have even braved loaning out my trusty Engel to family and friends, and it's still going as well as the day it was bought, and nearly looks as good. It's a very tough unit, which has coped with a lot of off-road action, it started life in my punch challenge truck!
