The Ram Ecodiesel is really just a grocery getter with no payload to do any real work. The payload is less than 1000 lbs so you really can't have a heavier tongue weight and people in the truck at the same time without going over GVWR.
That's simply not true. The only models with sub 1000 payload were the Laramie Longhorn 4x4 and Laramie Limited 4x4. As with the top of the line model with any manufacturer, the payload will be significantly lower than other models. Regular cab models top out at 1583 and Crew cabs at 1480 which is just about par with any run of the mill 1/2 ton.
OP - you're not going to find many on the used market. They only started hitting the streets around March/April and Ram expects to only sell maybe 20,000 at the most this year. Over at Fuelly it looks like people are averaging between 23 and 27. Most of the towing test have been with flatbeds or boats, but the reported MPG always comes back around 18. Probably closer to 14-16 MPG for a TT of that size.
The 5.7 might be a better option. If you compare the rated MPG of the two trucks and current fuel prices alone then you'll see that it's almost a wash at the end of the year. The 5.7 will have a similar payload, maybe a little higher. The 5.7 might be easier on the pocket book. The diesel is $2,850 more than the 5.7 and you can find a ton of 5.7s used. If you foresee upgrading in the future then the 2500 6.4L would be an even better option.
