While a prolonged major move has prevented me from working on the cap, it did force me to make progress in a roundabout way: the Leer fiberglass tonneau, late of a 1990s Chevy Silverado, had yet to be cut into two new smooth side doors. The intact cap was really ungainly, so I figured it was high time I cut out the desired pieces so that it would be exponentially easier to move and store. I measured the angle of the back of the cab and marked out my cut lines. 24 inches was the maximum height I could achieve with that angle, so that’s the height.
