Tired of carrying 2x6 boards for levelling.

I use Anderson Levelers and like them very much. I installed a large bubble level on my pin box so I just roll onto them until I'm level. What I like about them is I can control the exact amount of raising of the camper. Unlike with boards or lynx levelers where you are forced to raise or lower the thickness of what you're using. If you need to raise your camper 1/2" it's not that easy to do using any type of lego style leveler and to do it with boards you need a variety of different thicknesses.
