In the past we've used Agricover Lomax tonneau covers. However, they don't make one for the long box trucks. Then, maybe it's better they don't. Factor in the rear fenders and the imposing height of this pickup and flipping a tonneau open would be difficult.

We got our American Roll Cover from Scott at Mobile Living in Shelbyville, TN and I installed it myself (with the help of the family).

I like this cover a lot. It opens fully for gooseneck hauling, it's quick, sturdy, and creates a secure, dry storage option out of your truck bed.
