Proper installation is crucial for the optimal performance and longevity of your tonneau cover. The M-Series features a patented clamp-on track design for simplified installation. While the process is designed to be straightforward, professional installation is recommended if you are unfamiliar with truck bed accessory installation.
3.1. Measuring Your Truck Bed
Before installation, accurately measure your truck bed to confirm compatibility and ensure you have the correct cover size. Measure the length of the truck bed floor from the bulkhead (front wall of the bed) to the rear of the bed with the tailgate down. Round to the nearest inch. For example, 67 inches converts to 5 feet 7 inches. If your measurement is within a few inches of the specified bed size, it is generally compatible. If the difference is more than 6 inches, re-measure.
