GMC Folding Tonneau Covers

Easy install by myself in about 30 minutes. Simple to adjust at the end. Factory spray in liner, the clamp is too large to get within a foot of the end of rail near the tailgate, they state within 6" in the instructions, so one side tends to pull up 1/16. Maybe making a set of clamps half the width would help. I love the look but also OCD with the finished look. I noticed on both sides of the rubber top seal that runs the lengths curves in and out up to 7/16 of a inch. As if it is placed by hand at the factory and no guide for the employee to keep it square. Hoping it is not a defect to cause early failure just outside of the 5-year warranty.
