Gas Mileage for F150 5.4

I have a 09 F250 with this motor. If I drive 75 I get 6 to 9. If I slow it down to 60-65 I can push 11. Speed kills the MPG. But if your worried about this, your in the wrong hobby.

Trailer tires are generally rated for a max of 65 mph. Running 75 mph could cost you dearly.

2006 F150 Super Crew, 5.4, 3.73 gears. Truck weighs 6200 lbs. empty and trailer around 6300 lbs. loaded. Total weight around 13,000 lbs. Flat land on Interstate from 10.5 - 11.6. Around the mountains where we live and generally travel 9-10. I have heard some brag about 14. Don't believe a word of it, unless they're hauling a small PUP.

8-10mpg for every gas engine for every TT. Pulling two sheets of plywood through the air is the equalizer.

This is what I tell my wife...we didn't buy the camper to get good gas mileage. I budget for 8 mpg and do a happy dance when we get 11-12 mpg, and wince when it gets 6. If I'm traveling two-lane highways, I never pass an easy "getting in/out" gas station, once I get around half a tank. I have a 2010 super crew with the 5.4L...I pull a 30' BHS and I wouldn't have it any other way!

Truck in my sig, 5.4, 3.73 rear. 168K mi. Interstate unloaded in OD- 13-15 mpg. Pulling 5000 lb. 22' TT, Interstate w/OD locked out--10 mpg.

The worst I’ve gotten is 9 and the best, 17. But those are single tank mileages and not a good indicator. Overall, I’m barely shy of 14. But I’m pulling a 16’ 3000# TT with a 2001 F150 3:55. Air resistance of pulling a billboard through the air is the main culprit. In my case, I only drive the flats to the next mountain, so weight is a bigger factor to me than the norm. Your TT is a lot heavier, so I would guess you’d be in the area of 10mpg.

12 mpg highway 60mph mostly flat Florida. Toyota Tacoma v6 towing package. 4200 lb Jayco 26 ft

It isn't so much the weight as the drag and the wind. With the 5.4 in good tune, 10 mpg on a good day no wind and flat ground and then subtract based on grade and weather.

Newbie question:

I'm trying to get a handle on what to expect for gas mileage. My "new" 2007 Maxlite 23RS will be pulled with my F150 CrewCab 5.4. Is there a rule of thumb as to what to expect?

Good travels,

10 mpg plus or minus, usually minus. Mileage depends on loss of factors but on flat land with low frontal wind and on cruise control you may see 10 mpg. With no wind or a tail wind you may see a slight increase.
