Decisions....Gas or Diesel

Diesels don't like cold weather. They take a long time to heat up and stink up the air when they are idling. But for constant heavy towing or heavy loads, they can't be beat.

My neighbor told me that new regulations coming out soon will require emissions testing of diesels. And ALL factory emissions gizmos will have to be on the truck and working. I don't know if this applies to all states.
