Thanks. That is the most counter intuitive result I think I've ever seen.
I wish I could understand why.

On a side note, I didn't realize they made S-10 pickups with 8.2 ft. beds. (Mine is only 6.1 ft.) So I wonder if one can assume that the empty frontal area being ~4.1 ft long is the relevant property or is it really 50% of whatever size bed (which would be even more counter intuitive).

It does not look bad areodynamically to my eyes.
Yeah, I guess not, it just reminded me a little of a bulldozer scoop which
got me wondering if it's purpose was form or function.

As for mods the obvous is an aero shaped cover for the bed but you can't make it too steep or the flow will surely separate and you'll gain nothing. Your truck looks nice and those aren't bad mpg numbers either! Have you got disk brakes on that? If so Hows the pad wear since the racing disc mod?
Thanks for the compliment. It has disks in the front. I don't know about the
pad wear. They've only been on for about 2000 miles. Haven't heard any squealing from the wear indicators. I don't really do a lot of braking in my commute. It's nearly all rural highway and with it being a manual, I use DFCO down hills.
