Thanks for the reply, it's great to hear that your equipment hasn't loosened.
Maybe it's just what Hank mentioned in the beginning threads, once the nuts and bolts are tightened so many times they need to be replaced. Last fall I began towing the TT with my 2007 Ram 1500 4 X 4, it was hard on it especially since its towing capacity was rated at 8,200#'s, we had a considerable amount of sway even with the e2 round bar hitch in place so maybe I weakened the equipment.
