Have a new F350 CCLB and am looking for rack options to mount my Hull-A-Port Pros on. Thule has the Xsporter for $600 but I am wondering what other folks might be using to haul kayaks. I want to stick with the hullaport carriers since I'm already invested in them. The hullaports will attach to the cross rails on the Thule for sure. I don't know about other rack cross bars. Anyone got ideas or experience?
