V10 gas towing fuel economy

[noteven]

For those of you towing 5th wheel RV trailers in the 13,000 to 16,000lbs gross trailer weight rating with Ford gas V10's, what are you seeing for fuel economy?

A tubro I'm sure would help. Pending what year truck your starting with make sure the drive train can handle the extra power

While not a 5th wheel, the rig in my sig below,

When we are fully loaded with water and gear, GCW = 17,780#

The camper weighs 9,920# full fresh water and bikes.

2005 F350, 3 valve V10, 5 speed torqueshift tranny in TH mode, 18" tires, 4.10 rear axle. I only tow 55 to 60 mph. All elevations so far has been 3,000ft or lower.

I get between 7.5 to 8.5 mpg on a good day runnig 87 octane. Average is ~ 8.0 mpg. This will go up a fair amount if I could ever get full straight gas again. The ethanol blend we get pulls the number down.

The truck has no problem pulling and covers all my pulling needs. Although she does have a drink'in problem.... and a small gas tank... It's all paid for and I am not trading any time soon unless gas goes totally nuts (what ever "totally" is now a days)

Empty, I get ~ 12 to 13 mpg

Thanks for your responses so far -

I forgot to also ask what your truck's empty mpg averaged?

What if a guy had a V10, normalized for high altitude with a turbo kit vs. a late model smogdiesel?

Only time I get less then 10 mpg is towing up a steep hill.

Why does any of that matter, the statement I quoted was weight wasn't much of a factor, and my trailer is full size 25-footer.

I was wondering what you were towing and towing it with to get over 10 mpg.

yep, this is a pretty standard range for a gasser.

With the 10,000# 11ft 6 trailer I got right about 10
With the 12,000# 12ft 6 trailer I get in the 7's.

I owned a 2002 F250 V10 with a 3.73 axle. Had about 120000 miles on it when I sold it. It did get better than 10 mpg towing but wasn't the best tow vehicle in WY over mountain passes. I got 15 to 16 not towing. compared to 12 with my 2008 V10 with the 4.10 axle. However, I gave up the mileage economy for the better axle in the 2008.

V10 and "economy" don't belong in the same sentence. Less than 10MPG is guaranteed.

I still have my 2008 F250 V10 with the 4.1 axle. I got 9 towing a small TT and little over 8 towing my 20 ft stock trailer loaded with cows. Great truck and great engine.I never got much better mpg when I owned the 7.3 L F250 diesel. it was a 2000.

7-10. Size won't make much of a difference.

Lots of threads on this. I used to have an '05 drw with 4.10 and usually got mid to high 7's while towing. It could easily be less than that, depending on conditions. Its why I USED to have one.
