Any one with the 7.3 Ford . How is your fuel mileage towing and not towing. Are you happy with your truck?

Have 1800 towing miles with our 30ft 7800# trailer and it's done an admirable job.

This is 4000 mile averages with 3.55 gears:
Highway 70mph - 17.3 mpg
City - 12.4 mpg
Towing - 10.4

The towing figure could take a hit as we're headed to bigger mountains and steeper grades next couple of trips.

Same here. Very happy with the 7.3L/10spd/3.55

The first thing you need to do is let us know if you are talking about the pre-2003 7.3 diesel or the new 7.3 gasoline engine. I assumed it was the new engine...

I have a 7.3 Ford, tows great, transmission just had to be rebuilt at 310,000 miles. I tow 11,000 and get 9-11 depending on wind and terrain.

2001 F-250, 6 speed standard, 3.73 rear end.

Oh, you were talking about the new gas 7.3? That’ll probably be my next truck. SRW F-350 with a 4.30 rear end.
