Interesting answers to your question. I certainly agree with levelors under both wheels. However, as to where to place the level, for me it depends whether you have a home type of refrigerator or an RV ammonia based fridge. I've only put the small square level with circle in the center on the base in the freezer. I then level to that. Knock on wood, I haven't had refrigerator problems with my ammonia cooling refrigerators. Please keep in mind, when I give anyone my free opinion, you get what you are paying for. . . .
