I saw this over on TDR and thought I would investigate. Below is what I found:

Underground Dodge Ram with Low-Emissions 175-hp Cummins Turbo Diesel

The part I am interested in is the following:

"...The 175-hp low-emissions engine will be available as the standard rating with all Dodge Ram trucks specified for underground mining at all altitudes. Dodge Ram trucks currently in service with the Cummins Turbo Diesel engine dating back to model year 2004.5 can be recertified with the low-emissions rating by a Cummins- or Dodge-approved service technician."

I have also seen on another site shown below:

Underground Dodge Ram

...that showed this configuration was limited on how fast you could drive it, 25 mph or up to 40 mph. It would be nice to have those power ratings whenever you wanted them, like for highway cruising.

Anybody know what these mining trucks are like performance and speedwise?
