Take a 2.6 GenI SWB and put a 4D56 intercooled turbo diesel engine in. (will mate perfectly with 2.6 tranny bellhousing) Fabricate or locate an adaptable wiring harness to get it running.

Install a bio-diesel auxiliary fuel delivery system to run it off of vegetable oil. The way this works is you start the truck on dino-diesel, a coil heats the vegetable oil to a temperature/consistency that is combustible. Once it reaches temp, you switch over to vegetable oil.

Add an on-board filtration system so you can fill up at your local greasy spoon!
