"Had a roll in hard cover which took up too much of the box. Also allowed water into the box. Received new tonneau quickly and easy five minute install. Drove fron Florida to Canada. It rained heavily for 7-8 hours. I had cardboard boxes in back and they were totally dry. Very pleased." —Peter F from Leesburg, FL bought an Extang Trifecta Folding Tonneau Cover for a 2003 GMC Sierra.
