I am always ready to get out and camp, explore or fish. And with four daughters I am big on recycling. So I often pick up things from other truck brands. Topper is off of a 07 Chevy 6.5 box and fits great! And super light weight. Sealed all opening in it and the bed so it has been water tight so far. Bed rug was being discarded from a 2018 f150. Made a 2x2 14 gauge cage out of scrap metal inside the topper that weighs 60 pounds to hold the rooftop tent when needed.
