I had the same issue when I was choosing a folding cover last summer, and I finally found all the info I needed on https://tonneautrend.com/extang/ They did detailed comparisons with photos, explaining exactly how each Extang model performs under different conditions. The Trifecta is the lightest and easiest to remove, while the Solid Fold has aluminum panels and holds up better in bad weather. I went with the Solid Fold 2.0 — installation took me under 30 minutes, and the fit was perfect. The site even breaks down price ranges, materials, and compatibility with racks, which made it super easy to choose.
