Ford Ecoboost gas mileage and reliability???

More capacity. Certainly not more performance because that has been a downgrade. I was at the rear axle and GVW rating and barely had anything loaded in the trailer. Doable but had to be careful. Also wanted to start towing a boat behind the 5th and putting some stuff in the truck bed(generator, spare battery, boat motor). Miss the eco... it was a towing machine, especially paired with the HD payload package.

Here's a thread I made at F150forum about my test drive in a 2014 F250 with 6.2L and 3.73 gears. Engine had less performance than my 2008 Sport Trac with a 4.6L 3V engine. Why, the very poor power to weight ratio. The F250 felt very under-powered with the 6.2L as it's torque to weight ratio would equate to only 325 lbs of torque at 4500 rpms in my 5768 lbs F150. Would had equated to 286 lbs at 4500 rpm in the Sport Trac compared to it's 4.6L's 300 lbs at 4000 rpms. The F250 weighed 7167 lbs from the factory. 10,000 lbs GVWR - 2833 lbs Tread Act Payload rating = 7167 lbs.

Truck was very very nice in stability and ride but for heavy trailers, you really do need the 6.7L Diesel if you don't want to struggle.

The other option is to either get a 5.0L or Ecoboost HEAVY DUTY SUSPENSION Package which will net in the low 2000 lbs of payload with a 8200 lbs GVWR and 4800 lbs rear axle. I prefer the 5.0L over the Ecoboost but couldn't find a 5.0L Heavy 1/2 anywhere within a 200 mile radius. Alright because my truck came with a pretty decent 1582 lbs payload plus I got to get a locking axle, chrome package, larger tires and other options not available on the heavy half.

I'd consider the 5.0L as well. Its a great tow vehicle despite ecoboost owner's negative comments.

The F250 was featured exactly like my truck in the signature except the lack of a locking axle, it had the tailgate step, and had telescoping trailer mirrors.

I was really expecting better performance but never did the math to realize I shouldn't had expected much.

Mike, your math is correct but you missed something. There is an 11% reduction in HP/wt of the base vehicle but it will be used for towing.

If you consider my GCW was 15,500 with the F150HD, my heavier 6.2 will push that to 16650. Given those totals, here are some comparisons of the eco, 5.0 and 6.2 super duty.

365HP eco -> 385HP F250 = 1.8% lower HP/wt
360HP 5.0 -> 385HP F250 = 0.4% lower HP/wt
420TQ eco -> 405TQ F250 = 10.2% lower TQ/wt
380TQ 5.0 -> 405TQ F250 = 0.8% lower TQ/wt

So, you can see that even towing, there is a noticeable difference between the eco and 6.2 (particularly TQ) but I've basically stepped back to the equivalent of a 5.0. If you consider the torque curve of the 6.2, it's going to feel better than a 5.0 pulling the same weight.

Now I'll know what your setup feels like compared to an eco:)
