My friend purchased a stand from another Rver. It may be homemade??? It is a metal {aluminum?} tripod. The unique feature is that it has a round ball that swivels inside a large locking nut that you just hand tighten. You put your small round bubble on it, and within seconds you just manouver the pole to get it level. It works on somewhat the same as a celing fan that has a ball that hangs and makes it perfectly plumb. This setup is fast and real easy to level.Has anybody seen them and know where they can be purchased?
