I've been keeping an eye out for a decent used truck for awhile as I had sold off all my vehicles save my commuter car. Came across this literally just up the road. 2001 Chevy 3500 dually, 2wd with the 6.0 gas engine and 67k miles. Gas mileage is obviously poor but for $8500 it is by far and away in better condition than anything else I came across.

67k is pretty low. 8-lug rims. Looks like it'll tow 14,000 pounds. Ver' nice.

 
Many (most) trucks out here in that class have the flat bed replacement, often with very low sides on it. It's easier to hook up a gooseneck horse trailer, and makes for hauling lots of hay more handy. Of course, you have to have a cattle dog riding up front on the toolbox to be authentic.
 

I have an 01 2500HD with the 6.0. Awesome truck...still going strong with over 210k on the clock. Yours is a really nice looking, clean example. I'm sure it will do you proud for years to come.
