I have Yakima clamp on racking and crossbars for full size pickup, $350.
Info at https://www.amazon.com/Yakima-OutdoorsMa...ckup+truck+rack
Have around $500 in the set.
Kayak cradle not included, but if you really want it, $150. $200+ at REI, used once, rollers in the back cradle.
I'm getting too old to throw stuff up on top of a tall pickup.
