Yesterday I spent the day getting a few small items sorted out -- like -- the stereo that would download Sirius satellite but would not make any sounds. Worked fine on FM and the NAV voice etc - but zippola on Satellite. SO out it came - no direct replacement - so a new bigger version and different brand went in. MO BETTA!
While there -- the dealer had a Sportchassis (a brand) in with a Cummins ISC 350hp 1000 ft tq motored version so I tried to take a couple pics showing the difference. My truck is 6" longer wheelbase - and a completely different hood.
Not sure these pics give the right feel of the size difference - but in person it's an OMG!
SMALLER motor -- Cummins
12.8L - DD13 in my truck
