I have a 06 mega cab 2500 Cummings and love it but want to get a newer one but not sure if I should look for a 2012 or move up to something newer because they did change the interior and the motor. Any advise would be appreciated

 

The big changes are going to be the after treatment systems on the 13+ trucks. It is something that can be deleted, however don't expect that to last, the EPA will start requring them to have the Systems in place for inspections soon enough
