BEST PLACE TO CHECK FOR LEVEL

My advice would be to "level" to what feels good to you. This might take a little time, but will be worth it down the road. Lay in the bed and see how it feels. Even walk around and see how it feels. Open the doors and see if they move on their own. I wouldn't worry too much about how level the fridge is. The new ones don't require it to be perfectly level. Just because the fridge is level, doesn't mean that the rest of the RV is level. When you find that "perfectly" level spot, then mount your level. That way next time will be that much quicker. Jerry.
