Rod is dead on! It mounts to the cover. When GOBI built these, we mounted it on my bed cover and out three people up there, jumped up and down, took the rack back off and not a dent. So it's built and secured just as tough as their roof racks.

You do have to drill four holes and get spacers to go in there to guide th bolts. It comes with new gas shocks so you can still lift the cover and it will stay in the UP position.

Th eother option is to order it to it mounts to the bed rails. It uses a modified bracket an T Nuts to hold it into the factory track.

This rack does not interfere with the operation of the factory cover or midgate.
