What is your fuel economy while towing?

Avg around 9.5 with this set up:

Anywhere from 2-7'K elevation gain, some steep hills.
Speed Limit or flow of traffic
6112 - 285/75/17 - SABM - Banks PM on S4 - Unknown dual exhaust
Truck is typically around 6500lbs: Rear TRD sway - Recurve R3 WDH - Redarc
Trailer is typically around 5000 lbs... depending on fill level of 45g fresh.

 

No matter what I tow it is between 9.5 and 10.5.

What I have towed since purchasing the truck.

18ft car hauler with a Miata, lawn tractor and misc items. 1200 miles total at 70mph. Averaged 9.8.

18ft car hauler with JD 1025 and loader, and a JD 3046r. 200 miles total between 40 and 60 mph. Averaged 10.2

12ft enclosed single axle empty. 1200 miles at 70mph. Averaged 10.5

I was surprised by the enclosed trailer. I would have thought at least 12+ with it being empty. We will see what it does in May filled up.

 

The natural habitat of a Tundra that tows:

 

My 15 SR5 (rear air bags)... 7.3 in the mountains of Tn... not much better in Fl on flat land... But... I was loaded to the max as well ...
Pulled it like a dream...

We camped for a week on a generator.... was about $50 a 24hr period for gas... and then a week at some friends with hook ups... My total fuel bill for those two weeks in Tn. (from Fl.) was close to $1500 ... (GULP)....

 

Your gorgeous Bigfoot has excellent aerodynamics compared to my 30ft brick with pointy parts. I’m sure that makes a material difference to fuel economy.

8.76 mpg average while towing and hauling firewood on 40 mile round trips to retrieve the wood. That includes the 20 miles to the wood (unloaded) and the 20 miles back home (loaded). Lots of hills in between to conquer. This is keeping my speeds at about 55mph on the highway. I currently have oversized 265/75-16 tires, but i lowered my R&P to 4.10 gears. With my 4 speed auto trans i’ll shift into third while towing on the highway. For the steeper hills i’ll row my column shift lever down to 2nd gear. This all proves that the 1st gen tundra is the best...at getting the worst fuel economy.

 

First trip to the lake with the new Tundra iForce MAX, I hand calculated 12.7 mpg. I pull a 4500# bass rig. It was a relatively flat journey.

 

Dang near bone stock with drivetrain and suspension... lowest was 7.3, average 8.1 in the flats of Florida.
