The Chevy diesel motor is not a piece of junk one or two of the people we go camping with have the chevy and their just as strong as ours. Until the owners start adding a bunch of HP that they more than likely dont need. For the most part our motors are strong ( I think the best ) but like the rest look at the guys that complain about the Cummins or Chevy most not ALL have taken a great feat of engineering and made trash out of it. If you need that kind of power then buy it so you dont have to modify something that its not but as always TJMO
That's what the Chevy owners tell you but if you could monitor the GM truck towing the same load up the same grade behind your Dodge you would learn the GM Isuzu V8 diesel will downshift two or three gears to rev the engine into the power band of 2500 to 3200 rpm when your Dodge-Cummins will pull the grade at around 2000 rpm.
Several years ago when I was transporting with my old '01 Ram HO/six speed which had 3. 54 gears and over 300k miles on the odometer I met a woman fellow transporter at a Flying J in LaSalle, IL. She was driving a new GM/Isuzu and we were pulling similar trailers. We were both going west across I-80 and she followed me. We kept in touch on the CB.
As we got out west into the mountains she would lag behind on every grade until about half way up the grade then she would slowly catch up. I called her and asked her what her tach was showing as I motored up the grades at between 1600 and 2000 rpm in sixth gear. What I learned from her tach was when her truck stayed in fifth (top)gear she lagged way behind. When her automatic transmission kicked down to third and spun the tach she easily caught up. V8 diesels are not the same engines as our Cummins. They do produce lots of hp and torque but only at higher rpms meaning higher fuel consumption and faster wear.
No thanks. No Furd or GM V8 diesels will be parked in my barn.
