Well folks, I have it narrowed down to one of the two, probably a 2016 or 2017 is affordable for me. The cummins is reportedly a much better diesel than the duramax, some claim problems with the duramax at 200,000 miles while almost everyone agrees the cummins is a 500,000 mile motor. On the other hand the Ram trucks are said to beset with electrical problems and have more transmission problems? I have always liked Chevy trucks but finding that Isuzu builds the duramax makes me gravitate to the cummins. Anyone have a high mileage 16 or 17 or there about's year model Ram or Chevy 2500 or 3500 they can share their experience with? I like the gas trucks but I think if your planning on being on the road for extended periods the diesel makes more sense and will last longer. I like the new 20202 chevy 10 speed transmission but they are priced out of my range. I am leaning to a crew cab long bed single non-dually 3500 for a once and done solution. Going Mobile for a while.
