Re: GMC Duramax Diesel
There's no problem with the DuraMax. But on that year it will be paired with the GM 4-speed transmission. The transmission is not as strong as the Allison or Torqueshift, but will hold up if you stay within limits.
Main issue is the Express platform is lighter duty, so max GCWR is 16,000 pounds (vs 20,000 E350 PSD) and you can't a true off-road 4x4 conversion for the Chevy, due to its lighter chassis. You can get a Quigley IFS setup, but that's more for bad weather driving, then real off-roading.
