Most Efficient .5 Ton While Towing

I have a 2011 F150 3.5 eco with 3.73s and a 18 F150 3.5 eco with the 3.55s
I also had a 2011 F150 with the 5.0

I went with the 5.0 after the 08 5.4 I had and both sucked more gas than I care to remember...somewhere in the 7's towing pop-ups.

When I got the 11 3.5 it was night and day power to both the 5.4 and 5.0 towing


My 11 3.5 I have towed the trailer in my sig over 40k miles now and avg a constant 10.0 MPG's using 91 Octane or higher as it does give more power and better fuel economy by a .5 MPG for me.

My 18 3.5 I have towed the trailer in my sig over 7k miles now and avg a constant 10.5 MPG's using 91 Octane or higher as it also gives more power and better fuel economy by a .5 MPG for me.

I tow all over the northeast in the appalachians of Pa, WV, Virginia, and North Carolina.....alot of towing time in the blue ridge mountains.

Will I ever go back to the Naturally Aspirated V8 in a half ton.....NEVER
The 3.5 eco just tows that much better.

As for fuel prices in Pa 87 gasoline is around 2.55 91 is 2.85 and diesel fuel is 3.65 per gallon. The diesel would have to do much better than 3mpgs for me to ever justify the price difference plus the DEF and those killer emissions

That is my real world mpgs with my setup
Oh and I always tow with the cruise set around 65mph too

I understand you are only detailing pricing in your area, which is all you can do. However PA has some of the worst fuel prices of the surrounding states. Here in MD diesel is 2.85 and premium 3.05 regular is 2.29. Those numbers are quite different from your current pricing making the gas vs. diesel analysis favor diesel by a long shot.
However give it a month these figures can all change.
At the end of the day. If you tow/drive an RV you are going to spend some $$ on fuel regardless of your vehicle.
In my book there is no such thing as an efficient RV tow vehicle.
My diesel dually is basically as good as it gets!:R.....and it's not necessarily good:S
