I came across this a little late, but maybe this will help:
That's my truck.
The cover is the "American Roll Cover" from Truck Covers USA. It wasn't cheap, but it's well built, fits right and should last the life of the truck.
I ordered the cover with the rack tracks installed and initially used some Yakima towers and crossbars I had laying around, but changed over to some Front Runner track mount feet and bolted the rack directly to the rails.
Check out the whole setup here:
