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.
This cover is a really good looking low profile cover that was very easy to install. I recommend using 2 people just because it makes it that much easier. Fit was awesome with very little adjustment to do. Took it through the power car wash a week after install and water was minimal at best in the bed. Overall I would recommend this to anyone looking for a good looking functional cover for their truck. Best thing is it is made right here in the USA.
