My F150 has the 3.31 and it's about the same when empty but I drop to 14 +/- when loaded.

Yeah I know, it doesn't make sense to me either. Maybe I need to stop thinking old school.
Because your gearing and load is in the sweet spot while the lower numbered ratio probably causes the engine to add more boost to do the same work. More boost =more fuel.

There's no doubt in my mind that the gearing is better with the 3.73. It shifts smooth as silk and never seems to strain even on long steep hills. My F150 shifts poorly and I have to use tow haul mode a lot. Not so with the Transit. I have it but haven't needed it yet. The turbo lag isn't as prominent on the Transit either.

should have bought your transit in Mexico, I get 29mpg in town and highway depends on how fast you drive. At 55mph I can get around 40mpg, but at 70 it is more like 25-29. I have a 6 speed manual trans, fwd, 3 ton van, 9 passengers, 2.2 TDI which you can't get up there either, too bad, they are great little vans

Yea, but mine does over 100mph and I still haven't had the speed limiter kick in!

I'm looking at buying a high roof. Still unsure on the engine. I started wading through this topic but didn't get very far. Is there a synopsis or graph of what mpg people are getting for the 3.5 with 3.31 rear end and their specific roof?

Not a bad idea. But, quick reference chart does not exist. When you look for MPG numbers, make sure the references are for long-term use, calculated by means other than the dash readout. Otherwise, you get some crazy anomalies, in addition to the dash display typically being high by about 1 mpg.

For what it's worth, with my medium roof and that drive train, 21000 miles of mixed driving, my average is 17.4 mpg.

After 2 Years 30k miles and towing

Well, when its cold or windy and driving 70 i get 16 - 16.5. In summer I get 17 - 17.5. At 60 I get 19 to 19.5, in summer. I tow a tandem cargo trailer with 2,000 pounds and it is about 9ft 2in, it weights 2k and I am carrying 2,500 in van.....and when loaded I am about 10500 to 11000 gcw......I get about 12.5 just depending on conditions....usually driving 65 to 69. Had zero issues with my transit except normal recall, and side door chipping....Ive figured out to close it putting my hands in certain spots and being firm.

Our maiden voyage (2015 148" MR 3.5L 3.73 axle) from Ohio to NC through the mountains of WV and NC, completely empty, averaged just over 16 mpg. We did have the cruise set in the low 70's for most of the drive. So impressed with the way in handled the hills...didn't downshift once! Since we got it home, our average has crept up to just over 17 mpg driving mostly around town (still empty). Can't wait to build it out and see what it does.
