not bed extender friendly...
the Tail Gate brackets (when using the utility track system) end up being smack dead center of the bed extender brackets. the only way to install both, use the brackets near the bed window, and don't use the brackets by the bed extender. then you need to figure out a happy medium so you have enough room to use the bed extender and use the cam locks for the cover. this wasn't difficult, just took time to figure it all out on the fly.
I had never purchased a truck bed cover. I wasn't sure what to buy and spent a lot of time doing research and comparing prices. I am so glad I decided on this cover! It was a bit difficult to install (only because the directions were less than clear) but it took only 45 minutes or so and it looks and works great!
