Last year for Dodge or Ram 2500 or 3500 quadcab .

I was happy with my Ford Super Cab and looked at the lack of a Ram equivalent as a negative when I was comparing vehicles. I need more space than standard cab but really don't need the full space of a crew.

The 4th gen Crew Cab interior is light years ahead of the 03-09 QC.

wow, we love the CC, so much more room for passengers.
2009

They dropped the QC in the HD pickups with the 4th gens, so 09 is the last year 3rd gen body, with a QC.

Checking on nadaguides it looks like quad cab was a 2009 and earlier configuration.
