I have a 2015 F-150 with the 3.5 liter Ecoboost twin turbo engine, 6-speed transmission, and 110,000 miles. We tow a loaded 24 foot long, 7000 pound travel trailer which is 11 feet in height. On trips with the trailer we are getting 11.8 mpg. When we use the truck on the highway without the trailer we get 18 to 19 mpg. Is it normal for the mpg to drop to 12 mpg or less when towing the trailer?

What mpg's are others getting when towing a trailer?

Thanks.

Yup 11.8 is pretty normal. Not so much the weight as the wind resistance. The truck by itself is already a giant brick that you are pushing through the air at 70mph. Adding an 11ft high wall behind the truck isnt doing it any favors.

To pull that the 3.5 is going to spool up the turbo's. Spooled turbo's shove move air into the engine, ECU then adds more fuel. One of those "gotta pay to play" situations really.

11.8 is actually pretty decent with a trailer that size. The added air resistance is definitely the key factor as is speed.
With the 5er I'm happy with anything above 10 Mpg avg for a trip. On relatively flat highway keeping the speed to 65 MPH I can get up to 11.5.
Once I hit the mountains, It's all over. Then the weight comes into play as well. Love seeing the 99.9 <PG on the lie-o-meter going down the hills though

Agreed.

My trailer has a 25' box, 30' overall and 11' high. It weighs 7500 loaded. My average with the F150 was a pretty consistent 9.0 mpg +/- .5 towing around WA and OR. Seems that every trip included some sort of mountain pass or hilly area at 60-65mph.

The best I got was on relatively flat ground with speed limits around 55mph.

The 6.2 is about the same mpg towing but the truck handles the trailer better.

I have a 2106 with the 5.0, towing a keystone cougar 28ft weighing about 7300 lbs loaded. Trailer is listed at 11'4 and i get a pretty respectable average of about 13 mpgs when towing. My trailer has a nice curved front end and the propane tanks are recessed into the front with a cover that encloses them. I guess the aerodynamics of that trailer help me get slightly better mpgs than most ppl on this forum seem to be getting.

Anything over 10 mpg is great when towing a trailer. With a Polaris RZR on a 12' trailer I can get 11-12 mpg. Pulling my fifth wheel anywhere from 7-8.5 mpg. Pulling a 16' cattle trailer at 60 mph I can get around 11 mpg. The ecoboost is thirsty when it comes to towing

Geez, wish I could get 11 MPG towing!!! Then again I have yet been able to tow and relatively flat roads, mostly hilly.

I get 8.8 - 9 mpg at 65 - 67 mph. It drops to low 8mpg at 70 mph.

Wow you should feel lucky!!!!! I tow a snowmobile in an enclosed trailer and it weight's half what yours does and I get 9-10........but i also tow a 4500 RV and 9-10 in it also, but I would be happy with your mpg!!!!!

I agree with all posts, 10 mpg is pretty much average whatever engine you have, Thats what I used to get with my Mitsubishi Outlander v6 towing a small hybrid, 2008 F150 with 4.6 and I am still getting same with my 2.7 eco.

The only difference, the 2.7 does it a lot more gracefully. Less RPM and amazing amount of torque.
