H1 Duramax Conversion

I have a nice '99 H1, 4Door w/bed, Blk, 6.5TD, TT4, CTIS, Winch the works. I love my truck and use it as a DD for the last 5 years but only have about 31k miles on it and 18K on the new updated 6.5TD replaced under warrenty.

I do however use it for the occasional long trip and can see the up side of 2wd, MPG, power, and tire life.
Anybody here have a conversion? Why the 5-speed Allison and not the 6-speed? 22mpg possible? or is that down hill. Cost about 40~50k?

I would think about getting the new '06 but they don't have my body style anymore? I love the hard top 4door w/bed or slant but that is not made anymore?
What is the MPG on the new '06 H1 Duramax? and could you make it 2wd for the hyw?

Thanks, Jeff
