I have never had a unit that did not sit level. Like Leemedic above, our driver side has everything his does minus the furnace/HWH, but do have a washer/dryer on that side. Our rig sits level on pavement, hitched and unhitched. As long as your tires are wearing evenly, and no unusual problems towing, ie sway,bounce,etc, and suspension on truck and fiver are ok, I would not worry about it.
