I was replacing a Extang Solid Fold (tri-fold) with this TruXedo unit. The installation is a little more detailed than the Extang, but overall functionality (the roll-up vs the tri-fold) suits my needs a little better. Fully opened and fastened, the TruXedo offers much more usable space above the rim of the bed. The locking/unlocking mechanism is also a step up in design (it's the only real negative aspect of the Extang). Overall, I'm extremely happy with the TruXedo. Great cover.
