problem #1

May 252012

3500 Laramie 6.7L

  • Manual transmission
  • 7,000 miles

The 350hp Cummins engine in this truck is so weak that it doesn't even perform to the level of my 300hp Duramax. Both trucks have six speed manual transmission. Not only does the Cummins have no power it uses fuel at an unbelievable rate. If I am lucky I might get 14.5-15mpg on flat ground, empty. 6-8mpg pulling a 12000lb 5th wheel. While the Duramax gets 20mpg empty, 10-12 pulling the same trailer.
