I just heard that this cover violates Advantage Truck's Torza Top patents and will be removed from sale from it's distributors and the internet. The lawsuit was just filed. Most should be aware of imitations or copies made in China by Stylin, JC Whitney, AutoParts Whse, etc. I have seen one of these covers in person and the appearance against the Tonno Pro is no match. Those that have not seen the Tonno Pro to measure against the N-DURE cannot see the difference to know what makes them different. THis winter in cold climates the N-Dure owners will be able to tell. I have the Tonno Pro on my vehicle and has held up for many years. One must pay attn to hinge quality, and the quality of the vinyl. If the vinyl feels dry it will be subject to cracking over a period of months. I have also heard good things about the ProEFX tonneau cover offered online and a few distributors across the US. Just mu opinions, not to buy the cheap Chiineese junk. THere is a reason for the CHEAP price.
