I have noticed that larger DP models have hydraulic levelers, less large (39 & below) have electronic levelers. Is there anything to be aware of with electronic?
I would think a 1" round piece of steel is pretty darn strong. Their purpose isn't to lift the rig off of the ground but to level the corners out and stop the side to side sway you experience in lighter weight rigs when walking about. I'm a bit surprised your Knight has only a single (no matter how big) ram in the front.
