With anything in life...follow the money!I talked to DMV inspector last year that mentioned that new laws where comming for diesels in NC when he came to check up on us. It sounded like they are trying to make it like a emmisions inspection on a gas burner now. The equipment must be there and they will hook into your trucks computer. No pass no tags.
NC finally realized how many diesels they had registered in the state and how much money they were losing!
