My new rig has a functioning 3 way refrigerator so I know that leveling is important to its operation. My question, is leveling down the long axis more important than side to side. I realize that an uncomfortable drop side to side is not good but that would be uncomfortable for people too. So is some minor side to side out of level less critical than front to back for refrigerator operation? I have a Bal, but I rather not fiddle with it if some minor drift off the level ball is ok and won't hurt the equipment.
