Anybody else using one of these to tow?

We are complete newbies, so forgive my lack of knowledge. I bought a 2021 F150 with all the tow packages, including the new tow-assist module (replacing what used to be a decal, I think).

It has the 2.7 EcoBoost with 10-speed auto and if I recall correctly, a 3.55 ratio.

I’m pulling a 6600 lb. trailer with ease, but seeing mileage in the low 7’s.

Before I run out and trade for a 250 Diesel, any suggestions? And if I move to the 250, what can I expect in improvement, if any?

Thanks again for letting a newbie show his ignorance! We’re looking forward to this new chapter in our retirement life!

Welcome!
So as you’re aware, your truck is well suited for that size trailer.
Whatever you get with your gas truck will be similar with others. Maybe a shade better with a big gas engine and deeper gears but not much. 1 mpg maybe.
Diesel will do about the diffenrece in the energy density between the 2 types of fuel. Or about 30% better. Again, maybe more because a big diesel wouldn’t be breaking a sweat with that trailer. Real world driving the speed limits I’d expect maybe 12avg out of a big diesel.
Haven’t pulled with or even driven a 1/2 ton diesel pickup though.

How much frontal area does the trailer have?
How fast are you towing?

I get about 12mph towing my boat with my 2016 3.5EcoBoost. The boat is 8ft high and 8ft wide. Not as heavy but the wind drag is the most important element for fuel economy. My brother tows a similar rig with his 2017 2.7Ecoboost and gets quite a bit better fuel economy than I do.

I get 8.5mpg towing an 11,000lb equipment trailer.

You should be doing better with the newer tech and the 10 speed transmission.

My experience with a diesel is that it gave about 30% better fuel economy pulling my equipment trailer.

My rig is about 10’ high and 8’ wide. I keep it to 60-65 mph and haven’t put the truck in “tow mode” yet. It seems if I go any slower than that here in FL, I’ll end up as roadkill pretty quickly.

I’d be interested to know what your brother is doing to get better gas mileage with his 2.7.

Thanks again!

Try the tow mode, it may put the engine in a better RPM range for improved mileage.

I pull a 10'tall by 8' X 26' long flat faced car trailer. With a 4K car inside and the 4K trailer at 80 mph, I get 8-9 with an 18 Duramax. Its not a Ford but I really kinda doubt the difference would substantial. The comment on the wind resistance is spot on. I can pull 30K of equipment on a gooseneck and get the same mpg. If you made the change simply for the mpg increase, you will be driving for a long time to make that pencil out.

Payload? Max trailer weight? Horsepower? Torque? Rear ended is? No guessing, please. Tire pressures when towing...TT and truck? Why haven’t you tried what Ford thinks is good..tow haul?

IMHO, stay away from the diesel, unless you drive over 50K per year.

First, the upcharge for a diesel engine is quite large. Second, the price of diesel fuel (in my area) is actually higher regular. Third, the cost of oil changes and filters will shock you !

I can't comment on the fuel economy, but 2.7 MPG is pretty bad for a <7000 lb trailer.

My choice would be a F250 with 7.3L gas.

Your problem has a lot to do with the frontal area and that will carry over to any truck, though you are working the 2.7 a lot harder than it was meant to do continuously. The main way that the F250 will help you is if you get the 48 gallon fuel tank.

All Ford pickups are rated for 60 square feet frontal area bumper pull, 75 square feet with a gooseneck. The reason for the higher rating on the gooseneck is that it is closer to the cab and gets less direct wind on it. When my daughter switched from a bumper pull horse trailer to a larger and heavier gooseneck her fuel economy went up You would probably do well to get a camper shell that rises up in the back to maximize air deflection around the trailer. Or a gooseneck trailer with some aerodynamics up front.

See page 16 of the towing guide:

2021 Ford towing guide.

Are boats are probably at the 60 square foot frontal area but the pointed bow and raked windshield help reduce drag.

Good choice! A large V8 in a 250 will handle that trailer, and a much bigger one, while still getting decent MPG. A small turbo engine can make big power, but working it hard uses lots of fuel.

OP...the 250 will also have a much improved, stable towing ability, with a little loss of ride quality.
