Mounting this in a Chevy Colorado or GMC Canyon? These mounts are requred: https://www.victory4x4.com/product/VC-BRM-PC.html

Any cover where the structure or the cover itself extends more than 3/16" or so over the tops of the bed rails isn't going to work. We've had good luck running the Access Roll-Up covers in both the vanish and the original. You will need to trim the bottom of the mounting rails of the cover where they go over the rack mounts inside and add some extra gasket material for a good seal. Rolling it up is possible with both heights, but it's really a PITA on the shorter rack, so take this into account. A quick video about this coming soon. 

It's stronger than the bed of the truck, but unfortunately, we don't have an official load rating on these kinds of force on that. We've ran this design loaded down with an RTT, hi-lift, shovel, axle, and mountain bikes on trails all over the country without issues. We do recommend running our bed stiffeners with this setup for additional strength: Tacoma Bed Stiffeners

There are holes on this rack to accept an aftermarket led brake light on the rear of the rack.
