Personally I would be more excited by a 400hp diesel with a 100hp hybrid electric drive generator combo like Ford is offering in the F150. Just bigger and with a much larger battery so that the electric motor can make a significant difference while pulling a heavy trailer.

me also. making the diesel a "mild" hybrid with a big enough battery to capture the energy required to stop from 60 and/or an option to capture the energy from a 1 mile 6% downgrade with a 10,000 lb trailer would likely greatly increase in town fuel economy and boost power. With the low fuel consumption at idle, it wouldn't even need start/stop incorporated,
