Not necessarily worse with the F250 gas. What are the gear ratios for the transmission and the differential? Compare. I would hazard a guess that the F250's have lower geared (higher numerical ratio) differentials and more choice of ratios. What you are really interested in is torque at the rear wheels.

The trucks I've been looking at have 3.31, 3.55 & 3.73s.
I was trying to stay more with the 331 or 355 rear axle

You can easily adjust gear ratio by using bigger/smaller tires & wheels. You need to recalibrate or reprogram the pcm to shift properly & to correct the speedometer/odometer

If you're towing often get the 3.73 or higher. If occasional get the 3.55. 3.31 are garbage

Ford is using rear wheel torque not engine torque. Overhead Cam engine don't make low end torque. A muscle car with Overhead Valve engine Like Dodge Challenger SRT Hellcat can tow much better. An Overhead Cam engine needs a very huge gear to have a low end torque. The reason why all truck today are automatic is because it needs a Torque Converter to multiply Engine's Torque

WOW! Is this getting confusingly! E150, Ranger diesel, F150, F250, overhead cams vs pushrods, diesel vs gas, turbo vs NA, automatic vs manual, Australia vs US. I thought the original question was would an F250 pull my 7900 lb trailer better than the F150 EcoBoost.

Yes, I think a 6.2 gas with either of the available 3.73 or 4.30 ratios (3.31, 3.55 are not listed for the F250 gas) would pull better than the F150 EcoBoost with a 3.55 gear. The F250 would stop better and handle better. If your towing a lot the F250 might be the better choice. However for occasional towing I would opt for the F150 EcoBoost with max tow 3.73 gear for many reason including initial cost, fuel economy, smaller overall size and a host of others that would make it easier to live with when not towing.

Diesel? That's a different ball game. If you tow a lot, drive many many miles it might be a good choice but for me the initial cost and and higher maintenance cost ( l don't do oil changes anymore) don't make economic sense.

I do tow occasionally but why are you saying at 3.31 is garbage?

They don't offer the proper RPM for towing. You'll smoke your tranny before to long. That's why I made the jump to diesel recently. If all u do is log highway miles then by all means get the 3.31.
