I have (had) the 5.7 tundra, 2012. Around town 12-13 mpg. Highway 15-16. Pulling trailer below 55 mph 10, 65-70 - 8 mpg. Pulling 27 FB International ONYX. Braking inadequate unless you want the use the trailer brakes continually. In my opinion too light of vehicle as a pull vehicle, pretty much a good pull vehicle for a small utility trailer. Once I hooked a 20 ft utility trailer with a 5,000 pound tractor on it. At that time I had not installed a brake module. Needless to say, the next day I put one on. Thus final results, i traded it off for a 2015 Ram with a Cummings.

If the trailer brakes are adjusted correctly via the controller why would the weight of the tow vehicle matter? If the trailer is not braking sufficiently then the tow vehicle must stop more of the combined weight then I can see the advantage of a larger, heavier tow vehicle.

There are plenty of examples of CanAm towing Airstreams with smaller vehicles

The post bposted again below is what I actually got as described. Me thinks anyone saying they are getting the mileage they are alledging are "pulling your leg" somewhat.

Up North at 17.75

Just back from a trip up the Superior North Shore, for the Grand Marais MN art festival. It was a quick 1,480 mile 3 day excursion with just the Wife, dog, and I, and no trailer. Average miles per gallon for the entire trip ended up being 17.75 mpg, everything from interstate to just kicking around the backroads. All hand figured, as we don't have the fancy on board fuel economy figurer gizmo. Best tank was 19.1 mpg, a combination of 74 mph up the interstate, and 55-65 mph up highway 61 blessed with a decent tail wind. Worst tank was 15.58 driving into a strong wind all afternoon at 75-80 mph with everyone tired, and anxious to get back home. All tanks purchased were 87 octane. Truck has the 5.7 automatic, with the aFe cold air intake, a Corsa sport exhaust system, and nitrogen filled tires. Please don't ask if the added junk helps the fuel economy, it was all on there when I bought the truck so I have absolutely no idea.

2007 Tundra Crewmax 4X4 5.7L with 124,000.

Empty (not towing) I-5 at 65 MPH from Marysville WA to Olympia WA (100 miles) 18.9 MPG according to the factory installed driving computer. Same trip I-5 at 75 MPH Olympia to Portland (100 miles) 17.4 MPG.

Towing 7,200 lb 31' AS I get about 11.3 MPG if my speed is a bit less than other traffic (I'm not tapping the brakes as much). Its about 10.4 if I travel at the same speed as traffic. This is for flat driving. Mountain passes have a way of changing the MPGs'.

My truck brakes about the same as when I'm towing or not towing. I rarely touch the brakes down the I-90 pass as the transmission does nearly all of the work.

On my trip from Missouri to Utah and back about a month ago I had a worse of 9.9mpg and best of 13.4mpg. I would hand calculate every time I filled up. I tow about 60mph with Tow Haul on and manually shift from/to 5th gear when hitting hills.

Best mpg leg, 13,4, was between Gallup and Flagstaff on I40. Wind light, some hills, AC on 50%
Worse mpg leg, 9.9 between Hays, KS and Salina, KS, hot and windy, AC on.

Most miles on one tank 250mi, from Jacobs Lake to North Rim, back through Jacobs Lake, AZ to Zion (didn't use the truck in Zion) then back out to Cedar City, UT. 21 gallons to fill.
