2015 f150 5.0 king ranch 4x4. Just drove to miami fl from wichita ks. avg 19.1 mpg going down. picked up a boat and trailer, 2000lbs towing. On the way back got 11.4 mpg. GUESS ITS TIME TO FIND A REAL TRUCK!

As expected.

Yep. The 5.0 and 3.5 eco mpg are about that even towing small loads. I just towed a 5x9 at around 3k lbs for 1100 miles and got 14.4 in my screw w a 2.7tt.

Just the way it is.

I see nothing to cry about. You could have been driving a gas Super Duty and got 12 mpg both ways.

That's about right.

Sounds within the normal range to me. I get 21-22 mpg during day to day driving and depending upon terrain drop to 10-13 mpg towing. My old 2001 Explorer did 9-12 mpg towing.

Slow down a bit and your MPG's will get a little better with that light of a load. Unloaded, I can get 18 MPG +/-, I towed a 6x12 enclosed uhaul which weighed in at about 2,600 lbs and got a little over 15 MPG on back roads, towing my camper I drop to the 10 MPG range on the highway. The camper obviously has a much larger front surface area and weighs about 1,500 lbs more.

There is something else going on here. I get 18-19 mpg hwy not towing with my 2014. I haven't pulled my 3500 lb camper far enough to get a read on fuel mileage towing it yet. But I got 14 ish towing a utility trailer with 2 ATV's on it on a 1000 mile round trip about a year ago. Combined weight of the ATV's, other gear, and trailer was right at 2000 lbs.

Driving with a tailwind or into a headwind can make a big difference in fuel mileage. Last year we took a roadtrip from GA to UT. On the way back I drove into strong headwinds from Denver to Kansas City. Fuel mileage was 4 mpg worse on that leg of the trip.

Your speed matters to. Keep it around 60-65 when towing and you'll do a lot better.

I think it has something to do with BOATS in general.....I almost get the same mpg towing my boat 2000lbs as my 5000lbs trailer.....and I get better towing my atv on a trailer then my boat!!!!!

Expect about 1/2 of your non- towing fuel economy while towing then if he get better you will be happier.
A SD would get nearly the same fuel economy unloaded and probably 13 mpg.
