That's about right!
Some of these things you already know,
Keep the tires properly inflated, depending on where you drive keeping it under 60-65 MPH, Try to keep it in overdrive as much as possible, don't carry extra weight if you don't have to, and forget where passing gear is unless really necessary also regular maintenance is important. See I told you , you already knew these things , Good Luck with your new truck! ,,,,,,,,,hanky
