Best Tonneau Covers for GMC Sierra Pickup Trucks

There are several benefits to buying a tonneau cover for your pickup truck.

Not only do tonneau covers improve your truck’s aesthetic, but they also protect it and any precious cargo from damage.

Let’s explore how these covers can be a great investment and go over the best ones for your GMC Sierra

Does a Tonneau Cover Actually Save Gas?

One of the most common questions truck owners have is whether tonneau covers improve fuel economy. 

By providing drag reduction, a cover should help your truck become more aerodynamic and thus give you better gas mileage. But does it make much of a difference?

According to a 2007 Wind Tunnel study, having a tonneau cover on a truck reduced its drag by 5.7%. 

More importantly, the study noted that GMC Sierra trucks were the most likely to offer improved gas mileage when driven with a cover. 

The rule of thumb is that improving aerodynamics by 10% will offer an improvement between 2 and 3% in gas mileage. 

The study’s results thus indicate that adding a tonneau cover will improve fuel economy by 1.8%. 

Ultimately, you will receive a modest improvement in gas mileage for your new or used GMC Sierra pickup truck. 

However, other factors that may impact gas mileage include driving speed and the weight of the tonneau cover.

Is a Hard Tonneau Cover Worth It?

When you consider that one of the main reasons for a tonneau cover is to protect cargo, buying a hard one is a sound investment.

If you drive your truck to different places or you live in a place with extreme weather changes, a hard tonneau cover may be especially worth it. 

Hard covers also add protection because they’re harder to remove due to locking mechanisms. 

That means you’re less likely to have your cargo or groceries stolen. 

Additionally, harder covers offer much more flexibility than soft ones. 

Lastly, if you think about aerodynamics, you’ll stand a better chance of improving fuel economy by having a heavier design. 

That means a harder tonneau cover may give you the best bang for your buck. 

Do Tonneau Covers Add Value?

Tonneau covers increase the value of your truck by making it more secure and versatile. 

Without a cover, you will need to tie up any cargo you carry to keep it in place.

Your truck bed and valuables will also be more vulnerable. 

Whether you plan to carry heavy loads often or simply want the convenience of throwing groceries in your bed once in a while, a tonneau cover gives you a stylish way to add functionality. 

You will also be protecting your truck bed from damage, not just potential cargo. A tonneau will ensure your truck lasts longer. 

What Is the Most Secure Truck Bed Cover?

If you prioritize security over other features, it’s crucial to know which designs offer the best protection.

There are several types of hard tonneau covers: roll-ups, retractable, folding, and solid. 

Soft covers come in the same categories, but hard covers will offer the most protection. 

Out of all hard cover types, the most secure is the solid hard tonneau cover. 

That’s because its locking mechanism over the tailgate makes it difficult for thieves to break into. 

Though the solid hard covers will offer you ultimate protection, the best tonneau cover will depend on your specific needs. 

For example, if you’re only planning to carry small cargo, a folding hard cover may be best. 

On the other hand, if you carry expensive or valuable equipment for work, you want to opt for a solid cover. 


There are several great tonneau covers on the market, and they range greatly in price. 

Choosing the best cover for your truck will depend on several factors: what you use your truck for, how often you carry cargo, and your budget needs. 

Regardless of which one you choose, you’ll be adding durability and value to your Sierra.
