7.3 psd 4.10 gears, 13-15 all the time loaded or not.
99 K3500, monster built 454, 4-6 mpg
. It would tow like hell and smoke all 6 tires, then run out of gas. That was brutal to tow with 130-150 miles was an average comfortable fuel range with a 38 gallon tank.

Have 10' 4k lb arctic fox camper on it all the time... gets hand calculated 10-11 towing 5k enclosed trailer or 7k boat. doesn't seem to matter whether the highway is flat or pulling a pass or 2.

Why read 02's after the cat , unless seeing if the cat's working correctly ?
My vote: put them before the cat. That is where your true A/F ratio will be found.
Edit: Lol. I thought I was in that 496 tuning / fuel mileage thread. Oh well, most of those people are in this thread too.

2011 f-450 6.7 PSD with 4:30 gear. 12 MPG empty. About 7 or 8 MPG towing. Mpg doesn't change much if I'm towing an empty 29' enclosed trailer or if I'm towing the 38' donzi ZX. I usually run 72 mph. It went as low as 5 mpg when I had a 35mph headwind.
