5. Editor’s Note

Haig, who bought Gator EFX said that: “I’m giving only 4 stars because of the shavings, description of being flat black. I’d buy it again, it’s tough, scratch resistant and looks great.” 

We agree. In talking with the rep on-site and personal touch and feel, it was very clear that this option is the BEST value. Review

Compared to its sticker price, the cover’s Line-x liner places it in a significantly higher tier for durability and protection. Although we did not put the durability to the test, a recent 3,000-mile road trip through 100F temperatures and snow and ice did not harm the device.

We placed the drain tubes at the cab-end of the bed, and they have been fantastic as far as protecting the inside from interior water damage. Despite the pressure washing, commercial drive-through car washes, and several 6″ snowstorms here in Colorado that the cover has endured.

There is just a little amount of water buildup right behind the tailgate, and it is only 1-2 oz—nothing significant. This is more likely the result of gaps from the truck bed to the tailgate than a tonneau cover flaw.

The cover’s folding mechanism is quite straightforward, and for convenience when standing outside the vehicle, the cable that releases the lock on each panel can be accessed from both the left and right side.

The two arms that hold the cover up vertically are at first a little difficult to attach, but we’re viewing that as a positive indicator for extended usage.
