I put a 3.2 Igloo (from London Drugs) in the truck camper and it all worked, but that was with a bigger battery bank. See my post here on that. (BTW a slightly bigger 3.3 had a better fridge layout for putting things, but wouldn't fit in the TC--was an inch too tall)

Here is my initial testing results post
