The bulkhead clamps/hinge will NOT stay in place no matter how tight the bolts are. Came off after two times open and closing. I worked two hours to modify the clamps to stay on. The cross bows fall off after my 150 mile trip, EVERY TIME. Tonneau cover does NOT cover the stake pockets. Does NOT seal tight against bed rails. Opening the tailgate unlocks the cover itself. Locking system allows cover to shift right and left two inches. Lund has received the last penny from me.
