Fiberglass pans for this model of truck is hard to find, especially a quality pan. I did some searching and ended up with a urethane pan from Street Scene. I also purchased their hidden hitch. Both of these items have not been installed by me, yet, due to the amount of time that I have had this year to get anything done.
The new body style has indentions on both sides of the bed where the bumper wraps around the sides. The urethane pan is made to attach into these indentions to make it more smoth.
Truckin magazine did a story on a roll pan install, such as this and they made it look easy.
