Spoke with the Ram "Guru" on the Cummins Forum....thought I was right about it, below is his reply...he has quite a few connections with them in his 35 yrs. of working for them..also has the print outs showing when production started and when they were released...He's also the one that knew about some hold ups in production with the 3500's...
Here's what he sent me.
"Production startup for the 2500's was Janurary 7th. First 2500 released from the plant was January 26th. Tell him to take a picture of the door jam with date of manufacture on it"
Only thing that I saw as far as build date on mine was month and year unless I'm overlooking something..mine states, April 2013.. BUT, as you can see, they weren't released from the plant until Jan. 26th.....again, no big deal, but it doesn't merit calling people names.
