What about a gas truck with a supercharger of some sort. By the time you pay the extra for a diesel and all of its components, and the fuel is usually $0.50 more a gas with a power adder will be a nice choice as well. My 6.0 stock comes with 325 hp and 370 ft•lbf of torque. My added radix supercharger added 100 hp and 125 ft•lbf of torque putting it up to at least 425/495 and that is not including the cold air intake, headers, and full exhaust. That compares to the stock rear wheel 210 hp and 405 lb-ft of the ford 7.3. Just something to think about. Good luck with your search.
