sorry I missed your reply. I think the hieght is just about right. I would say about 10" higher then bed rail when down. I'll measure it tinight on mine when I get home. For a roof tent I think it would be great since it will keep it low but allow acces to your gear from the side. It will block your rear view with a tent but then again even if you mounted it even witht he bed rail you rrear vis would be shot based on how Scotts looks. These racks are stout too so the standard pr is all you need.
You could modify it some to change the hieght of it with minimal work. I was a little dissaponted that thule did not give you more then the 2 basic hieght adjustments but you could cut some more notches into the verticle post if ya want. Granted if ya go lower then on the new taco you will have to shorted the post off the bottom since it will hit the inside bed wall near the little side compartments.
