So FishOnOne, you decided that you wanted to let everyone know that the 6.7 Ford engine is doing so well that the mechanic has been trained to work on the 6.7 Cummins, due to what reason? I haven't said a a bad word about any of them, not any engine configuration...I had over 37,000 miles on my 2010 Dodge 3500 Cummins equipped dually, zero issues and that was me towing 15,500# plus, all over the mountains of WV, TN, NC, SC and VA...nary an issue, now I have the 2012...only about 3700 miles so far on this truck, without issue, but I would certainly hope it would be ok with only those few miles on it.
We know you're enjoying your Ford, I'm glad all is well, in the mean time, I'm enjoying my Ram...probably lot's of others out there enjoying their Chevy's and GMC's also...just talking diesels, so I stopped with the "Big Three"...
