When you think of a “combo” you most likely think of a fast food menu. These prepackaged meals usually give you a sandwich, an order of fries, and a drink. Judging from the popularity of the combo meals I would guess that a majority of people take advantage of the economical, convenient, and easy to order meals. What Dual Liner does with their bed liner is a little different, they took the best parts of all available bed liners on the market and rolled them into one bed liner, producing a “Hybrid” bed liner of sorts. The Dual Liner Truck Bed Liner is actually a “combination” of the “Drop In Bed Liner” and the “Rubber Bed Mat.” Dual Liner combined the excellent dent resistance with the incredible scratch protection and did away with any negative qualities that each of these bed liner had individually.
