Can I add more than 2 cross bars on my sport roof rack? Are all 4th gen cross bars interchangeable? Will 5th gen cross bars fit on my sport rack?
Any chance of safely mounting an RTT if I had more than 2 cross bars?
I left mine in place. They pushed up slightly on the rtt and I figured it helped some.For those with an RTT mounted directly to the side rails, did you have to remove your cross rails or did you leave them in place?



I would just mount to factory siderails versus messing with more OEM crossbars.
I make and sell a RTT cross load bar kit that mounts to factory rails if you want the RTT mount channel to orient front to back on the roof. Simple solution and only 4 bolts to remove tent with load bars once you get it setup.
Mine is mounted to the stock rails. The cross bars are to weak to mount to.
