I anticipate the tent sitting roughly 6 inches higher than the cab. I picked up the tent mounting brackets from Wheel Every Weekend that have proprietary nuts and rack specific mounting brackets so no one can steal my tent off my truck. I am running the Putco Venture Tec rack and was lucky enough to find a cross bar from Amazon for $30 when they are $230 from everyone else. Got the bar, it's new, has all hardware and the correct part number. Crazy Amazon sold it for $200 less than everyone else and it was the only one, haha.
