"I was surprised how easy it was to install! It was exactly what I hoped it would be. For the price and ease of installation, you can't beat it." —Thomas V from Thousand Oaks, CA bought a Lund Genesis Tri-Fold Tonneau Cover for a 2001 GMC Sierra.
"the extang tuff tonneau III installs so quickly and easily there's hardly any effort involved. the tarp attaches with ease due to the quick fastening system which eliminates the hassle of dealing with snaps. the 2 different heights for the cross bars make for easy attachment of the tarp in colder weather which is a plus. the click lock tail rail just further eases things. all in all this is by far one of the best covers i have ever seen/had, i highly recommend it." —Timothy G from Nottingham, MD bought an Extang TuffTonno Peel & Seal Roll Up Tonneau Cover for a 2001 GMC Sierra.
