I am too chicken to put my tire up on the roof rack. 60 sways enough in the corners. Where are you gonna put your High-Lift? I'm thinking to put it in the tailgate or on the back of the roof rack.
It is currently mounted in the roof rack with homemade mounts using 3/4 emt clamps, bolts and plastic spin on knobs. It actually works pretty good and is out of the way. I thought about fabbing a mount to attach to the tire carrier but I may leave it in the rack.
