Increased fuel efficiency, security and weather protection are some of the benefits of tonneau covers for pickup trucks. Tonneau covers are easy to install and appeal to some users by providing a sleeker appearance and hiding the junk that is often found in many pickup truck beds.
Tonneau covers improve the aerodynamics of a pickup truck by covering the hole created by the bed that traps air and provides resistance. This aerodynamic design reduces drag and increases the truck's gas mileage. Hard-shell tonneau covers typically have a locking mechanism that protects against the theft of cargo and tools. Both hard and soft covers protect the contents of the truck bed from rain, sleet, snow and hail. The covers also keep items from blowing out of the pickup bed while driving.
