Starting the new truck hunt
We currently pull a Flagstaff 26RLWS, 30' and 7500lbs or so, with a 2002 Chevy 1500HD. Ole Red is getting a little long in the tooth and it's time to consider a new tow vehicle. Looking at Ford, Chevy...

I don't know if the MDS technology is the same in the 6.4 as it is in the 5.7, but I can tell you we bought one of the first 2005 Magnums to come off the line in Sept 2004. First year for the Magnum, first year for the all-new 5.7 Hemi with MDS.
The MDS works in the 5.7 by redirecting oil pressure to deactivate lifters and keep valves closed while the PCM turns off fuel and spark to those cylinders. Sounded terribly complicated, so I got the 7/70 Dodge extended warranty because I had my doubts about the MDS technology. Here we are 13 years later, 142k miles, and the motor has never been opened, not even valve cover gaskets.
Apparently, it's still the same. Doesn't seem to be any issues with it. Probably extra points for Chevy for not having it but I don't know that it's enough to sway the decision.
