Diesel Truck Question

[phatdaddy]

I might have the opportunity to buy a 1990 ford dually diesel. The truck has 70,000 miles and i would be getting it from the original owner. The engine is the 7.3 International, no turbo or computer. I work out of my truck(96 Dodge w 5.9) , so it wouldn't just be for a tow vehicle. I was just wondering if anybody has any experience with this set up and given the price of diesel should i just look for another gas truck.
