Mine is usually 30-32. I do mostly around town driving of 15-35 mph. Occasionally go off road but that doesn't affect it because I don't run it hard. Mine is a 2018 and all stock.
Mine is a 2020 with the 538 gears mostly around town with some minor off road. I hand calculate at every fillup. Normal is around 25 but I have seen as high as 30.
I have a 2019 with 3.73 gearing and I'm averaging 29.5 mpg and I have 9000 miles on mine. It is tuned and has a DYI intercooler kit with the stock air intake. I run it around down and up mountains.
Street legal 2018 3.73 with stock bfg tires. Diesel Freak stage 2 with intake hold down. I check my mpg after every fill up and I'm getting 30-31 mpg consistently with normal driving.
