We find it difficult to maintain a consistent temperature in the freezer because the freezer door flops open very easily, and freezer items try to slide out. I recently bought some of these Camco cabinet bars and applied one to the freezer door - - it works well at keeping the door shut, and the freezer stays colder.
Also, we've found that objects slide around on the shelves and bump the thermostat. In order to stop this, I got one of these to make a little 'wall' around the thermostat. A piece of feedback I'd have for the fridge manufacturer is that the thermostat turns too easily for a bump-prone vehicle.
