There's just something about a roll-top tonneau cover that makes us giddy each time we see one in action. Maybe it's the perceived "magic" of "now you see it, now you don't" that excites us, but we think a lot of it is the exclusivity and feeling of just having something that every other guy on the block also wants to have. The most notable aspect to us, though, is that we're able to have the usefulness of a secured tonneau cover or the roominess of an open bed in an instant. Truck Covers USA has been building its American Roll Cover and other cargo-related products for more than a decade and offers a two-year warranty on its covers, so the company is definitely confident in its stuff.
