I just returned from an 1850 mile trip in my 2019 Tundra with 4100 miles on it. A lot of the miles were driven at 75 to 80 mph. Most of the rest were in the Blackhills, so lots of hills. Average was 16.5 mpg. Around here, I get 16.5 to 17.5. I've seen as much as 20 mpg on the readout but all these figures were calculated based on miles and gallons.
The truck has 4.30 rear gears and will pull. We took it on this trip over my wife's Highlander because I prefer driving the Tundra. I actually think it rides and drives better.
I'm totally happy with my truck choice and I've been a Ford fan until recently.
I got rid of my 2017 Tundra because it drove like crap and I am a loyal toyota customer. My SIL has a 2018 Silverado which drives way better then any Tundra. I have a Highlander for my long trips , I value my lower back.
