i think the reason i get such great numbers is mine is a 6speed manual...

 

Towing with the 6.7 will not get you great fuel economy. I see 10.5 to 12.5, towing a 26 foot bumper pull (rounded front and rear) at 62 mph. That is hand calculated and I have the deletes done. Running empty is another story. I can hit 20 without too much trouble, but I have to stay at 68 mph or slower and no wind.

For towing capability, the 6.7 with a 6 speed auto is truly amazing. When worked, the 6.7 makes power and to make power she needs fuel, there is just no way around it.

That being said, I have no problem paying for the extra fuel she burns in exchange for such a capable towing vehicle.

 

when i reset mine sometimes it says 99 or 75, 50 just kinda skips around
