Has anybody actually weighed the factory tonneau? I've never gone back and forth about something so much... I love the look of my tonneau but really want to put this truck on a diet. My only concern is, the truck already struggles for traction on street tires so is it worth it if I only get to the track a couple times a year? I don't want to have to take it on and off all the time... that's how scratches happen and right now its perfect.
