I am curious to see how the Ecodiesel actually pans out. I am almost certain this engine is heavier than the gas engine and wondering if it will effect the payload and/or towing capability because of the added weight? Obviously, we all talk about the advantages of the diesel for towing, etc. In my 2015 Ram 1500 Ecodiesel it did impact my payload significantly compared to the gas models with the same options. I also wonder if they will need to take away volume from the fuel tank to make room for the DEF tank. In the Ram I believe the DEF is 6 gallons. I'm looking forward to seeing the Ecodiesel in this model, I just hope it doesn't negatively impact the above. Time will tell.
