Do You Need a Bed Liner if You Have a Tonneau Cover?

A truck bed liner can be incredibly useful when it comes to maintaining the bed of your truck. It can be made of various materials such as rubber, carpet, hard plastic, or spray-on. On the other hand, a tonneau cover is layered over the top of your truck bed and gives extra protection from rain and added overnight security. 

You don’t need a bed liner if you have a tonneau cover, but it’s advisable, since it offers dual protection for your truck. You can install a bed liner as long as the products are compatible. Most tonneau covers will work well with various bed liners, such as spray-on and below-the-rail liners. 

If you are looking for a way to increase the protection of your truck, it may be worth considering combining a truck bed liner with a tonneau cover. Read on and find out whether you need a bed liner if you have a tonneau cover.

The Advantages of Having a Bed Liner and a Tonneau Cover

The common misconception is that a tonneau cover and a bed liner are the same, which is incorrect. A bed liner is installed under the truck’s bed, while a tonneau cover secures the bed from the top.

You don’t necessarily need to have both, but it’s often a good idea if you use your truck a lot to transport cargo. It offers you dual protection

A truck bed liner is a protective lining for the inside of the bed of a pickup or flatbed truck and protects the bed of the truck from scratches and dents. Tonneau covers are installed over the bed of a pickup truck, protecting its contents from outside elements. 

Tonneau covers can be removed when not in use, while truck bed liners are often a permanent addition to your vehicle. One can choose to install both a truck bed liner and a tonneau cover on their vehicle for maximum protection against rain or snow, cargo theft, and other external elements.

While a truck bed liner is an excellent option if you want to prevent damage, a tonneau cover is designed to protect your cargo from the weather and provide safe transport for your equipment and luggage. Combining these two things will provide you with the ultimate protection for your truck bed and cargo.

Bed liners are a great way to protect your truck from damage, saving you money in the long run. The benefits of bed liners are numerous and can be broken down into five categories:

Cons of Combining Bed Liner With a Tonneau Cover

Bed liners and tonneau covers can benefit your truck, but sometimes the two are not a perfect match. Combining these two products can have some adverse effects.

  • You may need to install a weather seal around the edges of the tonneau cover so that water can’t seep through and ruin your cargo.
  • Installing a tonneau cover on bed liners that go over the rail can be challenging. You may need to install special clamps on the bed liner to hold the tonneau cover.
  • If you use your truck to transport large cargo that goes over the rail, such as cleaning or gardening equipment, it may not be practical to use a tonneau cover.
  • It’s much more expensive to install both a bed liner and a tonneau cover than installing one product on your pickup truck.
  • Sometimes it can be challenging to find the perfect size for both products to fit on your pickup truck.
