This is something I built for the fridge years ago, had it on top of a set of drawers in the back of a ute. When it was tilted it sat on the tailgate, now it hangs in fresh air.
I have had to cable tie dividers in the fridge basket for obvious reasons....
It has a couple of large SS door hinges welded to the pivot point and bolted to the bench top.
I made a spring loaded pin that passes underneath and fits in a keeper bracket to stop it bouncing about also you can slide the fridge straight out, or by operating the pin the fridge will tilt.
The strut that limits travel has lost its gas so is only to relieve stress on the pivot point stopping it over rotating and damaging the seal on the door frame.
The tilt has worked fine for 5 years now and can not see it playing up now.
The fridge is getting a cage made from alum expanded mesh which stops stuff falling under the thing when its tilted.
