Hey Martyn good to always add to the debate

I'm an Engel man myself!
An independent fridge review was done over here - very worthwhile the read:

The Waeco did come off on top of that test but the general result was all the fridges were good.
Just to add more food for thought - In out club we have 2 guys who have used the Engel fridge locks on the back of there Hilux Utes and both have broken the plastic on them making them useless - not very impressive. We all now rely on turn buckles and strong mounting points - makes sure the fridge doesn't go anywhere.
