LOL missing the point the 6.6L wasn't installed in a 33K GVWR truck :haha
:thumbsup GM knew better :thumbsup
I'm sure if you looked hard enough you very well might find even 3 6.5's with 500K miles :wtf . . . LOL :haha :roflol: . . .
I'm sure it all "could" have happened but ya see here is the thing the 7.3/6.4 & 5.9/6.7 have done it so often the majority of the planet has seen it done :thumbsup
The D-max is a great engine i didn't say it wasn't makes good power too, Until D-max's reporting 500K miles start becoming a routinely done thing i'll remain skeptical of its abilities to run with IHC & Cummins sorry . . . No malice intended . . .
