Thanks to all, the third set of jack supports helped with the jiggle. I also had the same setup in my last camper so it was just a matter of duplication. It's all about trial and error. The shelf pullouts took a while to build ,the first one took a while to figure out but once I had completed that one the other three came pretty timely.
