A tonneau cover or a Camper shell, also known as a cap can be a great choice for securing the goods in your truck. Even though both of them make excellent solutions, it might be a bummer to choose one between them.
Tonneau vs Cap Gas Mileage
According to aerodynamics, an empty truck bed makes air drag due to its shape. A tonneau cover prevents the extra air resistance. Even though it may not seem significant, you can see a noticeable reduction in fuel consumption after a long period.
According to studies, one of the best ways to improve the truck’s fuel consumption is to attach a tonneau cover. Some studies show a tonneau cover can improve gas mileage by as much as 10% by reducing aerodynamic drag.
However, it’s unclear if a cap helps with better mileage or not. The shape is very less likely to help reduce gas consumption. If the cap/camper shell has a higher shape than your cab, it creates wind resistance which can result in lower fuel mileage.
