I have 48,000 on my 2008 and use it for some heavy towing. Had the soot bug worked out and love the power it has for towing. This is my 4th Cummins and added performance packages to the other three. The 6. 7 does not need it. It loves towing in the mountains where it can show up those towing with a Ford.
