I've got my eye on an '87 K20 Burban with a 6.2L diesel. How do I assess the engine? What kind of mileage (especially highway) do they get? It would be my first diesel truck - I have a a '91 V3500 with a TBI 350 - that I can no longer afford to fuel /forums/images/icons/frown.gif I'm driving a Sidekick instead, but I can't fit the wife kid, stroller, and groceries on the same trip. The other possibility is to do a diesel swap on the V3500 by finding a cheap donor truck. Any tips on a assessing a diesel in a running, but undriveable truck?
