I have a 2010 Challenger R/T with the six-speed manual transmission.

One thing I particularly liked about the car is that it does NOT come with the Multiple Displacement System (MDS). I don't trust the MDS to work properly, and I have to suspect there will be some weird stresses on the crankshaft with four dead cylinders.

My question is, why is MDS not available with the manual transmission?

Are there some "drivability" problems with MDS + manual transmission?
