My '93 Ford F350 dump truck needs TLC. "Plan "A" was to get a new one, cost
was $50K. So, I'm on to plan "B"

If the old girl got a new engine, new tires, new toolbox, new bumper,
sandblast dump box, and new paint job; I think I could get another ten
years. "The Kid" says I should get a diesel for it cause the gas mileage is
so horrible (7.5- 9.0). He's agreed to do the work if I buy all the parts.

Anybody done this? What engine should I look for? Hidden gotchas?
