you would have about 4" from the front of the bed with it rolled up tight and about 6" if rolled loose (measured from front bed wall where indention is to outer edge of cover rolled up). The side rails that attach to the bed rails hog up about 2" on both sides (measured from bed wall to edge of rail).
I dont think you would run into any problems w/ the fender hitting unless it really sticks out there.

 

Okay guys my Access LiteRider roll up cover has been installed, along with some AVS in channel window vent shades.

I will post pics when I get home this afternoon.

 

Awesome man can't wait to see...

 

Looking forward to the pics.. I purchased another one today in preparation for the arrival of the new truck. $278 shipped, not bad.
