Hey guys!
I have a few questions about which cover to get for my '07 Sierra (NBS). Which one would you guys go with overall? Better quality, fitment, installation, or warranty? I would like to get one that has a little more security since my tailgate locks. If you have any input I would really appreciate it before I go and buy one. Thanks a lot!

I don't know about the Extang Revolution, but have two Truxedo Lo Pro's....one on a 2004 GMC and another on a 2006 Dodge. Very pleased with the look, performance, quality, and functionality with the roll-up feature. When installed, the cover leaves room to put something in the stake pockets, such as bed rails. They are easy to install, about 30 - 45 minutes at the most, and the tension on the top is adjustable. The tonneau top has a lifetime warranty.

As for wear, the oldest one has been on different trucks over a five year period. It has been exposed outside to the Texas sun during the day and the heat, and it still looks good. Velcro on the rails has held up well, too. If I were looking for another soft roll-up tonneau, I wouldn't think twice about going with the Truxedo, again.
