Toyota rated our trucks at 16-21 tops but i get 17-18 since im 90% city driving and refuse to drive like an old man holding up traffic.
When i read people saying they get 22+ mpg I laugh cause not even when i was stock doing 60-65 mph with and without cruise control did i ever get even close to 20.. LOL
Especially since im a 5 speed and autos get worse mileage and a few have said they get 4cyl mileage haha
Our trucks sweet spot is 45-55. 65 is not. And especially nothing above that.
I'm with Madjik on this, don't get how everyone gets such poor mileage. I will say though that here in Colorado there is a 2-4mpg difference in winter, mainly due to ethanol, but I just noticed recently we're back to the good gas. So with that being said:
I do not drive like a great grandma with my V6 5-speed, and last tank, 100% city, 265/75/16 Load Range E BFG ATs, 2" lift, and sliders; I got 18.9 MPG. That is with the topper as well. When I try to get better mileage in town, I usually get about 21. Best I ever got (and repeated almost identically twice) was 26.2MPG driving between Steamboat and Fort Collins. Those who know that drive understand it is probably an average speed of about 50-55mph 2-lane highway with lots of curves and hills.
In fact, I'm in FC now, filled up in Steamboat, I'll report back with the millage I got when I fill up tomorrow or Sunday before heading back up.
Spend around 4-8k on the truck in armor and big tires and other shit till it is super tall in the air and weights 5000lbs..then you get 10mpg like me
