I have been told that the v10 is hard on gas. So what are you guys getting for mpg?
I have herd the 6.0 chevy motor is not good on gas either. My old 351 was not that great on gas.
My real world mileage for my 2000 V10 F350 CCLB 4.30 gears and a 8.5 ft utility box weighing 9600 every day was 10 to 11 mixed driving doing service calls and going to constution sites, sometimes lower if I was pulling a trailer, I had a electric & refrigeration business. In the winter it was less because it idled more so I could keep warm.
I added a procharger to my 2v, I had a not so good first venture so my fill up strategy went into the crapper. The last leg home pulling the toy hauler in the hills generally took under 1/2 tank with an average of about 6mpg. With the supercharger not boosting I burned just over a 1/4 tank. I was able to use OD and hold 3rd on the smaller hills.
mines an 08. It seems to like gas more than others for some reason. Bone stock crew cab 4x4, 4.10 gears. All city driving = about 7-8 mpg. highway driving, 10-11mpg. I have almost hit 12 one time on a road trip. Needless to say anything over about 200 miles its actually cheaper for me to rent a car if Im just needing to get somewhere and not pull/carry anything. I'm not in a big city so rental cars are cheap to rent.
7.5 mpg hauling 7-11k lbs the last few days. Just over 11 empty lately. Down from 9 loaded n 13 empty when I first got it. Truck doesn't seem to have the power it use to and has an odd stumble/misfire as well. Still troubleshooting tho.
Cruise set at 57 mph when I went to pick up my topper netted me 17.1 mpg on a 270 mile round trip. 16.8 on 320 mile round trip similar conditions a month after.
Just yesterday I delivered my HiLo camper (4K dry pounds) to my daughter, 160 miles away.
As I've perceived a slight occasional misfire (no codes) I decided to switch over to 93 octane, just to see if it'd help (it didn't). Pulling the trailer 160 miles (10 miles back roads, then equally spilt between 4 lane and interstate) at 5 mph below the limits then heading back home empty, running at the speed limit. At 250 miles I again gassed up. SURPRISE: I got 14 mpg on that trip.
Normally I run 87 octane around town, driving like your grandpa, and get 12 mpg.
NOTE: VERY LATE EDIT BUT I JUST REMEMBERED ... I DID MAKE ONE OTHER CHANGE JUST BEFORE THIS ROAD TRIP. I REPLACED THE AIR FILTER. IT HAD A K&N (AND APPEARED CLEAN) BUT I WANTED TO RETURN CLOSER TO ORIGINAL. CLOSEST I COULD FIND AT O'REILLY WAS A WIX ($20).

Reason: Just remembered
I get 12mpg consistently. Best has been 13.5. I am driving a 15 passenger van lightly loaded and usually towing a 16 foot equipment trailer. I have not done any tune up work, but just developed a miss.
