Last camping trip, as I was coming down the camper steps, one of the rivets sheared off, almost making me fall down. A quick fix was obtained by inserting a #2 Phillips screw driver in the hole where the rivet went.Once home, a permanent fixed was made with the following items purchased at HomeDepot:
Best to drill all the rivets out and drill a 21/64" dia hole and install a 5/16" gr 8 bolt and nyloc nut before another one breaks and someone gets hurt.
