I am glad that RAM took the jump and put a diesel in 1/2 Ton truck ( I own a jeep Liberty CRD with a 2.8L VM Motori Diesel and love it). The Ram Ecodiesel just can't meet my TT towing needs whereas my Ford F150 Ecoboost can. The best part about RAM going the Diesel Route is the option...some love Diesels (I am one of them).
For my Supercrew 4x4 : 1900# payload and 9600# towing (11,200 if you add the Max Tow)
RAM Same Config : 1040# payload and 7650# towing
By the time you add tongue weight and 1 driver...I would be over the payload capacity.
I still would love to own one...get www.GreenDieselEngineering.com
to do an upgrade on the ECU...and diesel down the road. On my Jeep the HOT TUNE from them did this:
HOT : 200hp/365torque
...and better mileage
If my 2012 Ecoboost was a 2015 with aluminum...I would have about 700# more to fool around with...
