I'm a trucker who is away all week and this is a gem of a fridge freezer, it sits at the end of my bunk behind the passenger seat in a DAF XF and is not in the way for me, but then I'm 5' 11" so I guess if you're taller it maybe an issue, when I put the seat back and a slight re line it actually locks the fridge in place so it shouldn't be trundling across your bunk, the weight of it stocked should stop that anyway.
I had it in a Merc Actros for a little while and it was OK in the passenger well with the passenger seat squab locked in the raised position, but on the diagonal as it is quite large.
I love the Bluetooth function so you can set & check what temperature the two compartments are running at, it also holds the temperature very well.
I love the freezer compartment, when I down in Cornwall I buy proper pasties, freeze them and bring them back home and when in Scotland I do the same with fresh fish such as mackerel and salmon etc
It is one of the better investments I've made!
