Wallew,
I'm in Fort Collins, about 1 hour north of central Denver. As far as the 855 Cummins goes, it's not a multi-fuel, but it's a BIG torquey motor and it will out run any multi-fuel any day on power, and will run just fine on pump bio-diesel. If fuel cost is a concern, keep in mind that a duece will get much better mpg due to being almost 10,000lbs lighter. As far as a winch goes, if you do actually want to run off-road, consider it a neccesity- because no one else will be able to pull you out. Also, the ability to run large super-singles is also a big advantage of the 5 tons (which will improve off-road performance and increase top speed). Here is a link to Oshkosh trucks- they are pricy on 5 tons, but it will give you an idea of what a 5 ton on 16-20s looks like.
