Well, for now, i'm getting one of the coolboxes with a 12v cooler unit on top from argos... it will last the week in Yorkshire which is all i need for now, but, i'm sure the missus will have forgotten in a few months then i can buy a proper fridge There isn't much in it - a Waeco one is only about £50 more than ARB
We hired a Waeco when we went to Morocco and it survived 2 weeks of rough terrain, running 24-7 without a single issue!
