A truck tonneau cover is a hard or soft vinyl cover that covers the bed of the truck. Oftentimes, it is also spelled as "tonno" cover. It is held in place by snaps, C-channels, or via a rolling-down mechanism. Using a truck tonneau cover will give you spacious trunk for storing cargo and protecting from bad weather and prying eyes.
The tonneau cover is also a great help in improving your truck fuel mileage. Normally, the aerodynamics of a truck bed don't actually fit well from a streamlining point. With the tonno cover, the airflow is smoother across the back of the truck. The roll-up truck tonneau cover best suits for cold-weather. As cold weather shrinks the vinyl material, the roll-up tonno cover uses an innovative latching mechanism to stretch the material automatically without the use of pliers to snap down the truck tonneau cover. Another plus factor is the support bows that shapes the tonneau cover. This means more space to the truck bed.
With the tonneau cover, there will be no more worries in hauling your cargo in the truck bed in almost all kinds of extreme weather and prying eyes.
