On my recent trip from ND to AZ and Back going thru Colorado on I70 up and over Loveland Pass at more than 11,000 feet my Ram 5.7 4x4 crew cab passed every chevy diesel pulling similar length trailers to mine like they were standing still. I was not pushing it. (I didnt notice any Fords on that part of the road pulling trailers)
These were new or newer Chevy's and this surprised me. They were stuck in the slow lane with about the same speed as the tractor trailers.
I have owned a deisel before a 7.3L Ford in the 90's but that was long ago and many improvements have been made.
I am very happy with my 5.7 it pulls like crazy and is very powerful. I don't see any reason to go to diesel with the gas engines getting so much better.
I owned a 2012, 5.7 2500 Hemi and a 2009, Ram 2500 6.7 with the lower output engine due to the manual transmision. I loved the 5.7 but it did not compare to the
6.7 and it certainly does not compare to a newer Dmax. You were blowing by them because they were much heavier or that was just their driving habits.
Anyway, sorry OP by the sidetrack. I really appreciate and enjoy your thorough reports on that 6.4, it sounds like a winner to me.
