All the Extang covers have a 10-year warranty on the tarp, so I'll bet it's the same material.
I don't like some of the hard tonneaus for the sane reason, jbrew. But the
FullTilt looks just like a regular tonneau cover, but the frame and all tilts up. I can also unsnap the cover and roll it back. The bows will not come out, though, without some disassembly. I don't like that fact, but, if I
know I'm going to be hauling something, I can have the whole thing off and in the garage in under two minutes.
