Perhaps problem solved..... Get the 60 litre......
Now..... Engle or ARB......
The Autofridge in our camper is on a slide, but I got the lid hinges moved from the long side to the short side (in factory), so that I can open the lid and still get some stuff out, without having to roll the fridge out. Just makes life a bit easier......
Lid hinging and control location are a couple of things to consider. The ARB and Engel lids are hinged differently.....ARB is hinged on a short side, and Engel is hinged on a long side.....ARB controls are at the front, and Engel's are at the back.
