Re: Picking the right train
I wanted to put my own 2 cents in. I drove cross country 2 years ago with my wife and 3 kids in an extended 9 month trip. We did this in our 05 Dodge Ram 3500 with a Cummins 5.9. I scaled our rig when we first headed out and found out I was way over weight. We were at 26,000 with a full tank and everyone inside it. I had driven our rig to Asheville and to Nashville from our coastal home of Georgia but never through the Sierra Nevadas or loaded that heavy. This engine did very well with no problems. We averaged 14 mpg and routinely got 24 empty and not towing. I had a chip on it and it was programmed to tow. We went to Missoula Montana and passed through some serious passes that made East side of the country feel flat. We left there went to Oregon and then onto Nevada. When we crossed the Sierras I was scarred but the 5.9 had ample power. I dont know for sure but it sounds like the problem is in the allison tranny.
I am seeking a Cummins motor basically for the ease of finding parts and the relative ease of working on them. Maybe this is just my experience.
Not all those who wander are lost.
