Just buy a Chevy in either the Vortex 6.0 or 327. Both are great engines. Most construction/mining companies that use 3/4 or 1 ton buy/lease either Chevys or Fords in either diesel or gas, I've seen a few Dodges on Right-of-way work, but that was most before 2007. As the saying goes, everyone needs a good Dodge diesel once in their life.
