Traveled over 1000 miles with these on my pickup topper. Only issue I had was having to tighten down the wingnuts that secure it to my rack. Had to make my own S bracket because I can't find anyone who sells parts for this. Great rack, have used it for 6 years with no serious wear and tear. Would like to get new brackets because of rust but no one offers any parts I can find that match. Time for an upgrade!
