yeah, i went for the model with curved side glass, because it blends better with the rest of the truck. i could have gotten opening side glass, but it would have been flat, without the "flow" i was looking for. plus, the dang truck is pretty much too high for me to reach in the sides anyway.
the rear section pops out, and has a screen, so that should be enough ventilation for camping trips.
i've logged my mpg since i've owned the truck, so i will see if i get any mpg gains.
