Friday when we picked up our rig a tech was helping us hook up and showing us the jacks. Each time we picked up the jacks in the same place and hit autolevel they came down different and though it said *success* a different jack looked like it wasn't carrying any weight. The tech said that was normal I said he was wrong. We towed it to a campgrund and did the whole unhook and then auto level in one motion and the jacks came down and leveled like a brick house. Ours is the 31 SL there's only the slightest movement in the living room and only at the very end of the rig. I'm going to try a pin jack under the trailer hitch but it's seems fine to me.
