I tow a 30' 7000 pound trailer with my 2.7L. It pulls great. Sometimes wish it felt a bit more stable but that is unrelated to the engine size. It's not bad by any means though.

Check out some threads I've had if you want more info.

The 2.7L with tow pkg should be fine with a gross trailer weight of 4K lbs. I currently tow a TT that weighs in at 3100 lbs without any problems. Other than the normal bumps, pops and lack of a rear view I don't know it is back there.

We are looking at a buying a new TT sometime next year. My limiting factor on trailer size is payload. For my truck that turns out to be about 7K lbs. Personally I think that is too high and still be able to keep my current sports car like driving performance. Based on this I am looking at TT's with a GVWR of 5K-5.5K lbs.

So I say go with whichever you prefer but keep in mind what you might do in the future. For us we will never need a large trailer so the 2.7L is more than enough. If we still had young children and were looking to a future larger trailer we probably would have gone with the 3.5L, HDPP.

Grey wolf 23DBH. 5200lbs dry. Probably closing in on seven thousand pounds loaded. It pulled surprisingly well but you definitely knew it was there. I bought the 2.7 before the trailer was a thought. I'm purchasing a 3.5 Eco with max tow because I want the extra capability and comfort level for cross country trips. Plus the extra 400 lbs payload and the longer wheelbase in the 6.5' bed will be nice while packing and for stability.

But for 4000 lbs I would not hesitate to recommend the 2.7. It is a great engine.

i apologize for thread jacking, as I said I was new at this and saw the thread tow this and it was exactly what I was looking for.

No worries, I saw the low post count and figured as much. I was just trying to pass on some helpful info.

The 2.7L EcoBoost engine is a great little engine that can PULL up to the GCWR with no problems.


The problem is payload capacity. The drivetrain can pull a lot heavier trailer than it can carry the hitch weight of that trailer without being overloaded. Overloaded = exceeding the GVWR of the tow vehicle. Payload capacity available for hitch weight = GVWR off the tow vehicle minus the wet and loaded weight of the tow vehicle (including the weight of the hitch).


It's very easy to overload any F-150 when dragging a travel trailer, so pay attention to details. The 3.5L EcoBoost drivetrain has a lot more GVWR and payload capacity than the 2.7L drivetrain, so I wouldn't consider any 2.7L drivetrain for towing more than a rowboat.


I love my 5-years-old 3.5L EcoBoost drivetrain. It's amazing.

I wouldn't say that. I have a lariat 501a with the 2.7L and payload package. My payload is 1718. I tow a 7000 trailer every now and then and it's fine.

Thanks all for your replies. I looked at some bigger Jaycos yesterday that were encroaching the 5000# GVWR and that helps with the decision go with the bigger 3.5 Ecoboost engine.

Make sure you check payload and the towing options installed on the trucks you look at.

Just the 3.5 Eb alone isn't the whole package for towing heavier.

For example: my 2016 is a 3.5 max trailer tow. But the payload is "only" 1606 lbs.

Works for me, but it's a heavy truck and that eats into my available payload....

And thus it Begins! Lol. Upgrading trailers seems to be the norm. Good call to go bigger just in case. I love my 2.7 but if there is any hint of heavier towing in your future save your money and buy the truck you will need.
