I have a 06 v8 sport i tow a 08 rockwood roo 21ss hybrid 4000 lbs +.I have to tow in 4th gear and i get 7 to 9 mpg. My roo is a tall trailer do to the slide out over the wheels.I was just curios if any one els is towing a htt with a v8 4runner and how yours tows.
I don't have a travel trailer but I do tow an 8.5'x20' enclosed car trailer that weighs in at 5,200-5,500 lbs.
Unless I am driving on flat ground I tend to always tow in 4th gear.
Having the transmission constantly up/down shifting between 4th and 5th gear is not a good thing.
Interesting that I tend to see the same 7 to 9 MPG that you are getting.
Lowest MPG I ever got was 6.95 MPG on a trip to Kalamazoo, Michigan last summer.
Flat Turnpike, higher speed limita and some headwinds did not help my MPG on one leg of that trip.

I see pickups with a roof deflector to 'break the wind' for the TT. Would one of those on the roof rack help the mpg?
Interesting question about the roof deflectors and their impact on fuel economy.
The front portion of my car trailer does sit fairly high above my 4Runner when towing.
After every towing trip I usually have to clean off the upper part of the trailer since it always is covered with dead bugs.
Guess I will have to visit some of the RV/Towing Forums to see if people that use the roof deflectors have seen a measurable increase in MPG after using one.
