Well if you're going to mount them without removing thoue headliner, you have to have some one sided mounting method. I've got these supports on my trailer used thru bolted and the racks use that way are very secure.

You have to realize that you're going to really reduce the selling price on that truck if you do this and ever want to resell the truck, specially on a relatively new one.
