I prefer driving the truck without the cap.. the window setup on mine is the single slider on the truck, and split slider on the cap, so in the rearview I have 2 bars from the truck, and 3 from the cap, so I am looking through 5 vertical lines, and then out the slightly tinted back window.. which is a royal p.i.t.a. to keep clean of roadgrime. Plus with my stepped cap, the truck does not fit in my garage.. so like this past week when I had to do wheelbearings I had to remove the cap. It is also a bigger side exposure for wind to grab and push me around. I bought the truck with it, so do utilize it during the winter and throw it on during the summer for camping.
