Yep, it's a 2005 6.0, I'm able to squeeze 16-19 MPG out of this thing so far, haven't tried biodiesel - although I'm a big advocate of BIO, it's just not near my route, and we're not driving as much as we used to, and now that we live in the city, I can't really make it (the biodiesel) anymore.
The PSD sure sounds awesome, and we can fit the entire family in the truck with luggage on road trips, AND we can pull the 9000LB boat! I'm pretty happy with it, for the first several weeks I had serious buyer's remorse, now that that's done, i'd really like to have my jeep back cause the ride was much better, hmmm, guess I still have buyer's remorse... WHYYYYY
Ok I really like the truck, I really like the truck,,,, boat boat boat.
