I have the ARB 60L on a slide of similar height on a Johnnos camper. It just fits through with the canvas cover on.
Its a good fridge too.
note the following
- if leaving fridge lid ajar when not in use, you probably can't slide it out with the lid still ajar
- canvas cover takes some height too (about 5mm or so)
- to open fridge lid fully (beyond vertical), you need to slide out the whole length of the fridge; make sure your slide is up to the task when the fridge is fullypacked and slide comes out such a long way
- make sure you have provision for plugging in the fridge into 12V power near the slide, as its not easy to reach behind the fridge once its on the slide (just saying)
- remember to consider some method to tie-down the fridge to the slide without warping the slide
