Here's a little info on the new Transit diesel:

Not quite 6.0 power, but weght-to-power will probably be close (at least for an empty van). Certainly beats the Sprinter. But then again the EcoBoost puts out 365 HP and there's already tuners out to crank out another 90+ HP. I do see the advantage with all-diesel appliances.
Also remember, its not a new diesel, only new to us. Hopefully the EPA stuff doesn't ruin it. So far I haven't seen much written about problem areas.
