Cummins New 5.0 V-8 Diesel?

I've been reading up on this new diesel engine from Cummins and have come to the conclusion, it would be a perfect motor for Class C & B+ motor homes based on either the Ford of Chevy/GMC Cutaway Chassis. There are different versions of this light weight engine, two to three hundred pounds lighter than your std. 6.6 or 6.7 diesel and the one that will power the next Nissan Titan PU truck will be 300 HP & 555 ft, lbs. of torque. I bet this Cummins weighs less than the Ford V-10 Gas! Just imagine the improved fuel economy. In a test Nissan Titan it registered 1,600 RPM's at 65 MPH. What say you? Bags.
Class C

    I think I'd like to stick this engine in my little S-10 Blazer! Depends on the degree of the pistons, though. Talk about a tree climber!

    It would be a great motor, but its not going into a class C cutaway chassis anytime soon. Until it does this topic is no more than wishful thinking.

    I think Ford is sticking to their own diesels, after the fallout with the 6.0 engine from Navistar. Chevy? Who knows.

    While I have long been a diesel fan going back to the 1960's (MB's, Peugeot, VW, Nissan Sentra and three different DP's), bottom line is that I suspect that Nissan/Cummins have an agreement as to who gets the engine. That is certainly how they worked with Dodge on the B engine.

    So, whether it would be a good idea (I agree) or not, doubt you will see it in a Chevy or Ford.

    I do think diesels are the way things are going long term, and I hope Ford does use an engine like that as a V-10 replacement option. For gassers, I hope they can make an EcoBoost V8, since this would be the next best thing for the V-10 replacement.

    I just wonder when diesels will get as reliable as they were pre-EGR/DPF/DEF. I read way too many horror stories about newer engines. A diesel does give better torque/HP/MPG, but there is just something simple about a gasser engine that just needs an oil change every 5-10k miles to keep it happy, perhaps spark plugs and coils every 100k miles.

    Add the cost of the diesel engine option verses the fuel savings first. The diesel engine in my pick up added 15K to the cost of the truck.
