There are only about 1,000 H1 HUMVEEs sold each year. Less than a few hundred thousand exist in total (that's over 20 years) including military, so your numbers are way off. There are at least 2 civilian biodiesel H1's in Seattle alone. Fort Lewis Army base is running B100 in every eligible diesel vehicle, according to the press and their web site. I imagine that includes every HUMVEE, since no conversion is necessary. That's probably a better percentage than any standard vehicle.

The German diesels may have that percentage beat, though. Seattle dealership(s) are selling Jetta's off the lot with biodiesel already in the tank. That's an excellent education and publicity program for biodiesel. (My truck has signs on every side advertising biodiesel and where to get it - and people are looking and reading).

The bottom line is that more vehicles of every class should become alternatively fueled. That's true whether it is a commuter, daily driver, or some esoteric machine that sits in the garage most of the time. We need to get Ze Germans to import more diesels, which means we need to educate Americans to ask for them.

While there is an element of humor in the tag line for this tribe, it sure seems like a better introductory slogan could be written. Why exclude the big, heavy, and practically pointless vehicles from the alternative fuel party? They're the ones that would probably help the problem the most by not using petrol.
