V10 gas towing fuel economy

When RVing the only thing tracking fuel mileage is good for is to let you know if there's a problem. If you notice a sudden drop in mileage, you better be looking for the cause. Other wise I agree with others, RVing and MPG don't go together.

Excellent point, tracking your mileage is like periodically taking the engines pulse and every bit as important as monitoring coolant/transmission temps and oil pressure. If something is going to fail you usually will get a warning in the form of change in these readings. You cannot have to much info which is just another reason to run a Scan Gauge. :C

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

X2 :)

My class C V-10 gets 9mpg. It is interesting to see these type of questions because I remember back in the '60's when gas was 16 cents a gallon and most cars got 10 mpg. I had a new Chevy pickup in 1971 and I never got more then 10 out of it unloaded. So I think MH and Pickup towing are doing well.

What if a guy had a V10, normalized for high altitude with a turbo kit ?

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

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?

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?

All gas engines, 7-10pg. Weight is not much of a factor, it's the poor aerodynamics of TTs and 5th wheels.

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

what are you towing and what are you towing it with?

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.
