Gas Mileage trailering?
#16
I see in your sig that you are running 20" tires. Have you checked to see if your speedo/odometer is correct? maybe use a gps to check them or the mile markers on the hwy. If your truck "thinks" its running on 17 or 18 inch tires your computer will be way off, even if you are hand calculating you will show fewer miles on your odo then you are actually driving and your calcs will be wrong maybe upwards of 10%. Just a thought....
