the f150 / f250 6.2's aren't built to the same spec. Different cams and tuning.

f150 6.2 = 411hp/434tq
f250 6.2 = 385hp/405tq

The towing 'ability' in this instance, therefore, is based on the frame strength (weight support/stability), vehicle weight, suspension and stopping power. that's why a lower hp/tq 6.2 is rated at a higher towing capacity 150 vs 250.

Both the Eco and the 150 version of the 6.2 are tow limited based on the f150 as a platform, not engine performance.

The 5.0 is a great engine with loads of potential but in stock form it does not compare to the 150 variant of the 6.2 for many of the same reasons the eco guys espouse - more power earlier and more total power.

I did not know that?? I just don't understand why Ford would put the 6.2L in a heavier F250-F350 with less HP & Torque then the F150???? Makes no sense to me...

The torque curve on the 250 6.2 is a little better suited for towing but I think maybe it allows for incremental enhancements. I have no idea why really.

The 150 is 411/434 on premium and 401/434 on regular. I 'think' the 250 numbers are on regular.

There is a ton of potential with the 6.2, the heads flow extremely well - just swapping in some mild cams and adding headers takes you over 500/500. Problem is, cams are freakin expensive - ~2,500 IIRC from Livernois.

I have the 5.0 and its not the weak point when towing my 5500-6500 lb 27' travel trailer. It's the soft suspension and tires. The truck has fine power, but the stability is less than id like. I've heard the hd package is much better, so no matter what engine you get try to get the hd package.

If your going to tow a trailer like that, your crazy to not use a 250 or better. My old 2000 F250 w/ 5.4 tow package, was a tow monster. Empty was 16mph on the highway, but towing even my small 17' boston whaler, it got 15mpg.

Like the above poster mentioned the soft suspension on the 150, also people reporting bad mileage (6 to 7), with the eco towing small trailers. (there's a thread here somewhere on the subject)

I average around 10mpg towing my 7500lb 33' trailer with my Eco with no issues what so ever. If there is someone actually getting 6-7mpg towing with there Eco something is obviously wrong... I had a 2007 5.4L F150 before this truck and i couldn't get better than 12-13mpg around town and 16mpg on the highway empty and only 8-9mpg towing a 5500lbs Hybrid trailer.

Very well said. I just wish they would set their recommended limits in the manual basically the same, with the only difference being for engine/trans weight. Someone should have enough common sense to relize that the smaller engines (course options like the ECO add extra work for the dealer guys, but thats why they are also there to push options like that) along with the internet. One should understand that they will probly hurt/kill smaller (cheaper) engine options quicker if they work them hard...well, that gets tossed out when I think of the old 4.9 I6 years ago. Many used hard, things like elevator work pulling anhydrous tanks and such, and outworked the larger 5.0. In short time I'm poking holes in my own idea, but you get the picture. Weight ratings in their manual shouldn't rely on which engine you choose, should be more of a recommendation than rating.
