I've had and both, stock to stock, the single wheels had more power and got better mileage emty and loaded. DRW had 4.10 and 4.30 with 285/70/17, singles had 3.73 and 35" tires. Anyone ever dyno there trucks stock. I did on my single, it had 260hp and 420tq @4500' above sea level.
Thanks.

I'm not to sure were you are going with this. I've always been under the impression that a drw is for added stability/ load control. Not necessarily more power/better mileage.:shrug:. If its my misunderstanding I haven't had my coffee yet this morning LOL

All the DRWs i've drove and pulled with wouldn't keep up with the single real wheels. This is on 6.0 and 6.4 motors.

Wouldn't 4.11 with smaller tires pull better? And weight is 500lbs different don't really feel 500 when your pulling 20,000 lbs. Lol. Mileage is the extra tires, not sure why I posted mileage. Don't really care about that. Lol.
Anyone dyno a stock 6.0 dully?

Well isn't in drag racing for instance every 100lbs is a 1/10th of a second. So if it is 500 pounds heavier let's say that would be half a second slower hen the same truck. Unless they lie about the power they put on the valve covers as well.

Or maybe its all one big conspiracy

Power:weight then throw in gearing. Simple physics.

The end.

Drive both, pull a trailer with both, then let you know what you think.
I have 91 gallons of fuel and I can't till if it's emty or fuel when I'm that heavy, that's about 800lbs. When your that hevey you can't really fill 1000lbs.

I know, but they will be close. But I have pulled with 5 6.0 single, 3 DRW and all the singles ran the same and ran way better. I was just woundering if I'm the only one that has noticed this. No I'm not racing them. It's just a big difference pulling.
