I have to chime in. I had an 01 7.3 SD crew cab. I had so many problems with it I couldn't take it anymore. So I traded it in on an 06 (brand new at the time) Dodge Ram Hemi. This is the best truck I've had by far. The power is more than enough for towing a GN on a dual axle trailer. I would have to say it would outpull my powerstroke. Acclerating, braking, you name it. That's with 5k pounds, which is the most I've pulled with both trucks. I'm sure in the 12K pound range the tables would turn. As far as diesels, look at all the hot shot drivers, they are driving Dodges. Look at the DHRA, the most powerful diesels are cummins. No truck will out perform the Cummins Dodge.
Supercoupe, I have a TBSS, too. 13.9's stock family truckster. I can't get enough of it either.
