If you sacrifice precious bed space for the security of a truck toolbox, you really care about security. But what about the rest of your gear—the stuff that doesn't fit into that diamond-plate bank vault? In the past, you had to gamble on a bargain-bin blue tarp or one of the few tonneaus made for toolboxes, which weren't much better. But now, you can keep your toolbox, and cover your bed, with the best bet in tonneaus—the Extang Trifecta Toolbox Tonneau Cover.

Featuring everything that makes the original Trifecta a sure bet, your Trifecta Toolbox cover is assembled and ready to rock right out of the box. With the straightforward design, all you need to do is put it on your bed, tighten the clamps and hit the road—go from uncovered to covered in 3 minutes flat. And, that's with no tools, cutting or drilling needed at all.

Along with the easy installation and made-for-toolbox design, your Trifecta tonneau features the legendary look that sets Extang apart. And, that sleek style is for more than just looks, it can also improve your fuel mileage. Ease, style and economy—now that's a Trifecta worth betting on! Best yet, Extang backs your Trifecta Toolbox Tonneau with a Lifetime Warranty on the frame and 10 years on the tarp.

Easy to install.the only thing I don't like is it doesn't sit as flush on the tailgate as it does on the bed rails

Very happy

The Extang Trifecta Toolbox Tonneau Cover is a good quality and easy to install cover with no tools needed. The only problem I have with it is the rear of the cover only hooks on the plastic rail and not the metal rail. If my plastic rail ever fails, I won't be able to hold down the back of the cover.

Easy to install and lightweight. Good bang for the buck

Only draw back was it is not water proof. Easy fix, got the same seal that you would use if you were putting a camper on the back of the truck (30 bucks at Advance Auto) and now its sealed everywhere but around the tail gate.

extang trifecta tonneau highly recommended.

Very nice tonneau. The big improvement over the past design I owned was the tool box adapter plate up front that accommodates several size boxes. It seals the bed nicely and allows easier access than a full tilt style although it takes a few seconds longer. It's also easier to remove the tonneau for large loads and it stores in your back seat. It works great.
