Thanks for the advice. Here's two other brands. Roll n Lock and Retrax. Any one ever use them?

As for the truck itself. When I had the race boat we had a Ford F350 Turbo Diesel Dually (What else

) to pull the boat. And I loved that truck.
This time around we drove the Ford, Nissan, Toyota, Dodge, and Chevy full size trucks. The Nissan drove the best and the accessories that come with the bed are terrific. The Nissan won the four wheeler magazine offroad contest. Nice 305 HP overhead cam motor and super plush ride for a pick up.
