While Titan announced cessation of the 5.0L V8 Diesel engine in the Titan, many of us held out hope that the 5.0L V8 would end up still being supported and manufactured by Cummins for school bus and RV markets. Well, that is also a no. After further research, Cummins basically had two main customers for the Cummins 5.0. (a) Nissan for its Titan XD, and (b) Tiffin Motor homes, used in the Allegro Breeze.
Well - the Allegro Breeze has a 2019 model, with the Cummins 5.0, but the 2020, goes to the tried and true, 6.7L model used in Ram trucks.
Also - additional research indicates the switch by Nissan and Tiffin may have been forced upon them by Cummins, as Cummins wanted to cease production of the 5.0. This is also further supported by the fact that they no longer market the 5.0 on the website at all.
My 2 Cents
If anyone has looked, there is a 2.8L Cummins crate engine, which they are pushing. In addition, prior to the 3.0L engine craze in the 1/2 ton category currently, Ford was looking at a 4.4 or 4.5L diesel for the F150 back in the mid-aughts to late aughts, only to be derailed by the recesssion. The history of the 5.0L Cummins was an original Dodge project back in the late aughts, which was derailed by the recession. Notice something common? Effectively, I think the Cummins 5.0L could have been in the same dustbin of history as the 4.4/4.5L Power Stroke, but because Nissan swept in to take it away from Dodge once FCA decided the market was limited, it was given a second life.
It sucks, because obviously, this means we 5.0 owners will lack for parts, service centers, and aftermarket products. But also, this could be over time, a collectors item for diesel fans, because these engines will be a rare, rare bird, in an over-built truck that, if Nissan is consistent with their reputation, will last a long, long time with an overbuilt design meant to withstand 1 ton truck level effort.
