I was pretty happy with my Rextrax-Pro tonneau until last spring when the plastic side to the roller box broke, I called up their customer sevice and was flat-out told the warranty had expired and they would be happy to sell me a new one for $2500+ sheckles, after arguing it's a lousy design to begin with, the whole side is mounted with self-tapping screws that are counter-sinked into the plastic and upon close examination the pressure of the screws caused small cracks that spread out to the edges and failed which was pretty easy to see on both sides but retrax stuck to their guns and I settled on a new top at 1/2 price. All I wanted was two new replacement sides which I would have installed with #8 1" stainless pan heads but no dice. I ended up epoxying the broken side,refastening it properly and sold it used for $800 so I recovered most of my cost but no way would I recommend retrax again as their after-the-sale customer service is lousy!
