I know I already had my chance to comment, but I figured I'd say one more thing about this.
If you don't care about color match, the Duracover Tonneau is almost exactly the same.
Duracover Toyota Tundra Tonneau Cover Review | tundraheadquarters.com
Duracover makes OEM tonneaus for Chevy and Nissan, and they also have the same tough abs plastic top with the snap on/snap off hinge setup. Considering it's less than half of list price (and install is easy enough), I would pitch it as an acceptable alternative.
Again, just so long as you don't care about color.
Otherwise, I hear what you're saying about fiberglass tonneau's - they don't look that great, they're heavy as can be, and they're just about the same amount of money.
