I migth be taking a trip to California from Alaska soon. I have never been on a long trip with my truck to be honest I have never driven this truck for more than two hours as I live in a town with only 20 miles of road. So I am wondering what I should tdo to prepare my truck for either adn 800 nile trip or an 1900 mile trip not sure which route I will be taking yet. How would you prepare your truck for a long trip like this???
