Mechanics say the 12 valve Cummins is the best. They are both good.
Friend of mine's a Dodge tech - and tells me the new Cummins is having a ton of problems, but I cannot recall in what way, although he did mention that one guy who just bought one (80K$ dualie) gets 25 miles and the truck goes into 'limp' mode... Dealer hauled it back - fixed it and he got another 25 miles and it went right back into limp mode... Three times now, and the guy's right pizzed... To me, that sounds more like a software issue not necessarily related to the engine.. I hope to learn more next time I see him..
