I towed a 28' tandem axle enclosed with a loaded toolbox and a 1965 F100 about 300 miles, I have 3.73 max tow but I also have LT285/65R20 tires and I only saw about 8 mpg but it still pulled with absolute ease and stayed in 5th or 6th gear almost the whole way. it also only had about 2000 miles on it at the time.

I definitely think the E rated tires help, the stock P rated were a little squarely even with my 24' TT. My 35s are E rated like yours

Gotta break them in right

Considering it IS only 213.7 cubic inches, the lower rpm's when towing REALLY surprised and pleased me. It is so much more pleasant towing with the EB that you can do 350 to 400 miles a day easily. In the 5.4, I was worn out after 250 miles or so.

We have the 5.4 in my wife's expedition, its there if needed to tow just in case but mainly used for the family. We don't all fit in my truck lol. I do like the EB torque comes at a lower rpm and it does tow well.

I agree the LTX tires made a huge difference in the comfort for towing.....at the expense of a bit of ride quality, I admit.

haha yep, the three brand new vehicles I have bought have been driven fairly hard from day one and I do really believe that this helps to seat everything properly and minimize oil consumption.

I did 1500 straight miles in my 2010 5.4L from Madison, WI to Missoula, MT with a Uhaul open car trailer loaded up with my 2002 Grand Cherokee, two canoes, and both the bed of the truck and the back of the Jeep packed to the gills. it was 24 hours of driving non-stop and it was horrible. I don't think I saw 5th or 6th gear at all, mostly 4th in WI, MN, and part of ND, but once I started getting into the mountains I was pretty much only using 3rd gear and going up over the continental divide I had to pull over because the truck just decided it was time for a break. I was at about 6000ft elevation and climbing and it just stuck in 3rd, would not downshift anymore and sure as hell wasn't making it up the hill. temps were fine, it just couldn't seem to do it without a half-hour cooldown. I certainly was not over the payload or towing capacity either. on top of that, I averaged about 5mpg for the trip with 3.55's and stock tires.

every time I have towed with my Ecoboost I could almost forget the trailer is back there. even with my catback, you could hardly tell it's putting in any effort at all.

Now, THAT is a great story. Like I mentioned earlier, the 5.4 would tow, it just often did not sound that happy about it. With the torque peak being at 3,900 (IIRC), and being a big old long stroke V8, it just did not sing a pleasant mechanical tune way up there.
When we were towing the heaviest of our three TT's with the 5.4, and then switched to the EB, it was, quite simply, hard to believe the difference in how quiet and capable this much smaller and more modern engine is!

I tow a 8X20 cargo trailer weighing about 5500# and the EB tows it with ease.

This is the funny look I was getting at before. Can you avoid the rear end dropping so much ?
