Even the "Allison won't fit" argument doesn't hunt. They've built the D-max Express Van with the 4L85-E, and I'd own a Diesel Suburban even if I had to take it with a de-rated D-max. It's been "comming next year" since 2001. I stopped holding my breath on 9/28/04 when it became obvious that it wouldn't happen for 2005, and I bought the flex fuel Suburban. It's nice, but I'd rather burn LSD than E85. (Although, the way the price of diesel has stayed above the prices of gas and E85 the last couple years I think I'd have spent more to fuel a D-max.)
