I don't remember for sure but different than yours. Same tranny but we ran 22.5 low pro tires and looks like your running a smaller tire. Are yours the 19.5? Probably the same effective revs per mile. 2100 is right where that engine builds it's Peak Torque so your best cruise speed is going to be between 60-70.
