Cheaper and more rugged than a tailgate cover, the Kuat Dirtbag Truck Bed Mount is a killer way to attach your babies (your bikes) to your other baby (your truck). These steel beauties screw right into your truck bed, and Kuat made models that are compatible with both thru-axles and quick-release dropouts, even for fat bikes, so you can find one that'll work with all your whips.
