Good food for thought.

I have a diesel Excursion that I use pretty much exclusively for work (hauling supplies and parts internally, or pulling a 24'x8.5' enclosed trailer). It gets nearly 25 mpg at 55, but only about half that pulling the trailer. I drive it about 10,000 miles a year, but those tend to be longish (300-4000 miles) trips at highway speeds where it would benefit the most from even modest aero mods.

I gotta put some thought into this.
