I would guess that either engine is capable of doing what you need but with that heavy of a trailer, you will probably need both max tow and HD payload to stay within the payload limits of the truck and that will limit your choices.

My Dad has a Super Duty with the 6.2l, crew cab long box. I have the crew cab 157 ecoboost. I have towed with both. I know they are not exactly the same setup, but I can offer my .02.

To me, I like it when towing that the engine doesn't downshift a lot, especially up hills. The 6.2 has good power, no doubt about it. But to make that power it needs to be higher in RPM's, which means downshifting. I find downshifting going up hills annoying, but thats just me.

My ecoboost can tow 7k against wind and up smaller hills with no need to downshift, the turbos spool and it pulls you right over.

When towing a lighter load(under 3k), it seemed the 6.2l did better than the ecooboost on fuel consumption. With heavier loads, 7-10k, they appear to get similar readings.

The biggest adavantage to the ecoboost is that empty you will hopefully get better mpgs, hopefully leading to a cheaper lifetime cost of the truck. This can be debated as some have not seen great empty numbers.

I do a decent amount of towing and the lifetime average is at 14.7 mpg in 14000 miles. I often wonder what I would be sitting at had I opted for the 6.2l.

The 6.2 does sound MEAN though.

any idea on what is included in either package that would require both.
My truck is fine with the weight now. I am looking strictly from performance comparison. I can order any package combo with these two engines in a Lariat from what I can tell.

I would personally go with the 6.2L but that's just because its going to have less of a load on it. How much do you drive the truck outside of towing?

For me the choice would be --
If I planned on towing ~40% or more of the time I would go 6.2L
Under 30% of the time definitely EcoBoost. I tow 4-6 times a year so I went EB.

No real hard data why I feel that way.

The biggest difference between the two is the max payload ratings. OP didn't say if he was looking at a 2wd or 4wd but in 4wd the 3.5L is better by about 200 pounds for the max tow package and about 650 pounds when you get the max payload. In 2wd it is the same 200 pound advantage for the 3.5L but about 800 pounds better with the max payload.

Can you define less load? Curious cause pulling 7k at 72 mph I was staying in 6th gear at about 2k rpm. In that vid he's doing 60 mph at 1700-1800 RPM, I would imagine they would both be running similar RPM's at similar speeds. 9.6 avg mpg is what I would expect my truck to get with that load.

not sure of parts differences but I believe max tow adds 500# to payload capacity, HD adds another 500#.

If you're looking at a 4x4 SCrew, your payload will probably be less than 1400#. Tongue weight on a 9,000# camper should be between 900# and 1350# (10-15% of trailer weight).

If you look at payload ratings and tow ratings on these trucks, its almost a joke. Real world, without HD or MaxTow, you will just about always hit payload limit before tow limit unless you travel alone and with nothing in the bed.

I was going to post the same thing.

And again, no real reason for why I feel this way.
