Warranties are essential when choosing a truck cover. Do not be fooled by fancy mirror pockets and custom covers, these truck covers do not have good warranties due to all of the extra seams incorporated with custom fit covers.
The type of cover to look for is one that does not have mirror pockets but has extra material to accommodate for the mirrors without folding them in. These types of covers will most likely have an extended warranty of at least 10 years and it will provide you better protection for your truck. Make sure that the warranty does not have exceptions or contingencies. If your cover has a ten year warranty make sure normal wear and tear is covered.
Make sure you have a checklist when shopping for the best Roll-Up Tonneau Cover. If your truck cover does not fit correctly, it will not protect your truck to the maximum level. The type of material is crucial to your cover purchase also in order to avoid damage to your vehicle.
The last thing you would want is to harm your paint when you were attempting to protect it. Lastly, the warranty time frame and its conditions must not exclude normal wear and tear.
