The trailer's frontal area matters as much or more than the weight. I just returned from a round trip from Ohio to Montana and back, towing a flatbed trailer with vehicles. About 6500 lb. I averaged 13.8 mpg roundtrip (4970 miles) running about 65-70 mph with premium in my '13 Crew ecoboost. I used tow/haul mode and locked out 6th gear most of the time to keep engine RPM at 2000 or higher.

Speed is the biggest factor. Especially with a large enclosed travel trailer with large frontal area. I've found if you average 60mph instead of 65mph it can save you 2~3mpg. Also so folks get better mileage if you stay off of cruise control. This seems to defy logic, but they say it allows you to coast (faster) down grades and/or get runs for the climbs. With cruise enabled you're slowing down on declines and hitting heavy acceleration on the climbs (with no run).

Personally I use the cruise as there's already enough going on while towing.

Personally, I don't think it'll get much better. I have a '13 FX4 3.55 gear CC. I average about 7.5mpg towing 4-5k lbs in the winter. I always burn premium, 10% ethanol for the most part. I tow like a maniac though sometimes at 80mph..


Speed is definitely my problem with the mpg's.

I have 2013 FX4 Ecoboost with 3.55 lifted 8" with 37's and pull of around 11mpg towing my 6000 lb boat / trailer. What help me the most was MPT tow tune , AFE stage 2 cold air and Cosa DB exhaust helped a little. Tow around 60 mph

I think locking out 6th and staying close to the 2000 rpm suggestion is the best suggestion. My Toy hauler is a wind hog and 7 mpg towing is Normal for my rig.

I get 8-9 towing my 3500-4k lb boat with truck in signature. usually between 65-75 mph. less than impressed. I have tried to go 55-65 but it doesn't make a difference. maybe .5 mpg.

using the other truck with 3.55's (2013) it is almost identical. if you find a way to break 10 let me know... I sure cant.

Buy a programmer with Tow Tunes!!
Mine works great!!

If your always in the boost (towing) 9-11mpg seems to be what most people around here get, the elevation may be higher up in VT but seems normal for a v6 towing that much weight

Yep, to do much better, you have to find a way to avoid physics!

I've towed my travel trailer (30', about 6500 lbs) w/ 2 different Suburbans, a 2500HD Duramax and my Ecoboost. The gassers have all been in the 8-10 range, the diesel did a little better, but truthfully not as much as I was expecting -- it was 10-11, touching 12 under perfect circumstances. There is just a lot of wind resistance at freeway speeds, and there is no getting around the work you have to do in order to counter that resistance.

FWIW, I've towed lower profile trailers that weighed a few thousand lbs more than my travel trailer does, and they towed much easier and w/ better mpg.

The difference b/t the F150 EB and the other gassers is how easily the EB tows at 65 mph, not the difference in fuel economy. No more 'cruising' at 3300 rpms in 4th gear like I have to in the Suburban!

Absolutely!!

My EcoBoosted Flex is very noticeably faster, and I have a 2000 F150 with a 5.4 that I got one for as well and it runs SOOOO much better. Shifts smoother, better MPG, more responsive.
