When I was shopping for trucks I was driving a Ford F-150 “2011”. This is the first Toyota I have owned. The dealer did informed me that the Tundra was a nice truck, built well, but gas mileage was poor. When I drove the truck the impression I felt was this is a solid truck! For the first 3000 miles my average mileage was 12.7 mpg around 5000 miles the average is now 15.6. My hi-way mileage is around 17.8 mpg @ 70mph and is 15 mpg @ 85mph (live in Montana). I always receive a compliment about the ride a feel of the truck from my passengers. I enjoy driving the truck and would not think twice about purchasing the truck again.
I bought a 2017 SR5 5.7L, 4wd, Crew Max, TRD version. If you want fuel economy this is not the truck for you (if you can get 11 mpg you will be lucky). This 5.7L engine comes standard with 4.30 gears in the differential (which are not highway gears but low end hauling gears) thus the pitiful gas mileage. The TRD package comes with tires better suited for off-road and have a miserable tire roar going down the road that you have to turn up the radio to hear it. I recommend just getting the 4X4 package unless you plan on doing a lot of off-road. The SR5 has no handle to grab to get into the drivers set which is a big step up to get in. All the other three doors has a handle to assist you getting in. There is only one USB port in the front cab, so you will have to use the two 12v power outlets. This SR5 has a stiff ride and the seats are hard and not very comfortable on that long road trip. My F150 was much more comfortable. Overall a very good truck with a few flaws.
