Read on Cummins forum from the resident dealer over there, he said order banks close in June. They may still build those orders through August, but, that would put the 20s on a normal release cycle. The 20s will likely be the same truck, still in Mexico (I did see the blue streak will be replaced in 20). I think 22 is the best case for a true 5th gen.

Not available to order on my Cummins 3500 SRW that I ordered on Mon., Apr 8.Has anyone been able to confirm the availability of 4.10 on srw trucks?
