I've had mine for about 2 years now. One of the first BOMBs I did. I have the stainless steel ones. I ordered them after someone posted here their experience with them. They said they had a 300 lbs (+/-) friend jump up and down on theirs and the whole truck shook but the bars stayed right where they were mounted with no flex or movement.
They were real easy to mount and have held up very well (no rust or discoloration). My only complaint is I wish they had a set that went back all the way to the real wheel. I'm short and reaching over the edge at the front of the bed to get to items is not easy.
