What kind of mpg's are you guys getting towing around 3000 lbs? I went to the mountains this weekend got 9.8 mpg both ways. My truck only has 2000 miles on it so I hope it gets at least alittle better.

 

2009 f150 xlt long bed straight cab 5.4 3:55 ls 18000 mi. Just returned from pulling an enclosed cargo trailer in the same weight range as yours from Kansas to Douth Dakota and back. 65 mph both ways. Low of 10.31(headwind), high of 16.750 (tailwind). Overall average 12.96.

 

i just towed my 5k travel trailer from Ma to northern Ny 1000 island region and back averaged 11.7 on the mpg computer going 60-70 mph

Im at 8K miles with 3:31 gears

 

With my 2007 Lariat Supercab 4WD pulling a 5k lb travel trailer I averaged just at or under 9MPG on 300 mile tow trips. With my 2010 Lariat Supercrew 4WD I haven't towed it much yet but it appears to be improved. I'm towing it this weekend for the first real test and will post my results.

 

I towed my 3500lb boat with 4 adults 350 miles today and the computer was reading 15.5-16 mpg but the computer is always 1-2 high vs. hand calculated. Thats about the same as I got with my 06 STX too.

 

Just towed a utility trailer with 1500 pounds in it and got almost 15 according to the computer.

 

Towed a 3500# camper trailer a couple hundred miles just the other day and got 12 mpg. Pretty happy with that.

 

I just towed a 7500lb trailer from Ohio to Florida and averaged 8.5-9.5 mpg. I have a 2009 screw with the 4.6L and 3.55's.

The biggest thing that kills you when towing isn't necessarily the weight, it's the size. A bass boat or utility trailer simply doesn't catch the wind like a box trailer or RV. It's that huge wall of wind you're forced to push that really hurts when towing, especially the mileage, LOL.

 

My boat & trailer weigh just over 6100# with the pilothouse on the boat the height of a semi cab. Towed 700 miles over the weekend & averaged 12.5 going, but running into 30 mph head wind on return brought overall down to 10.9 on return.
