Thanks Truckdaddy.

Excellent info!

I am trying to find a cover that will allow me to carry my bikes in the back when open. Not sure I can make it happen with a retractable. With the shorter bed of the crew cab its tough to lose any space up front and make it fit! Seems like the
TruckCover is the way to go. I'll check them out to get specs on how much space it takes up in the front. Seems to be more than 8' from the picture you posted.
