I did a lot of research to find a way to mount my RTT without having to lose my tonneau cover. Settled on Billie bars because of the strength and durability. Once they arrived one bracket had subpar powder coating exposing the steel. Contacted BB customer service and they had a new bracket set out immediately.. no questions asked. These Guys are great to deal with. Product is strong. My only regrets is they came out with the 6inch ones too late. Would have loved to have still seen under the bars and roll the tonneau up. Maybe a future upgrade.
