I’ve got a 2016 TRD Sport. It should run forever, but it won’t win any races and it’s not the fuel miser that you might want a smaller truck to be. After the mods I added (AT tires, lift, led lighting) the mileage is around 17mpg. Newer ones perform nominally better, but I’m not a fan of 4 cylinder engines with turbochargers as far as longevity. It’s no tow vehicle either. If you tow regularly, you’ll want a bigger truck
