The fridge is supposed to be level, so I leveled using a bubble level in there. I then placed the bubble level on the wooden part of my center console, and of course it was not in the circle, but I circled where it was with a marker. Now, I just put the bubble level there and try to get the bubble in the marked spot. I have checked back in the fridge several times and it is always right on. This just makes it so I can level from the driver's seat - just getting older and lazier.
