Change the oil at least a couple of days before the trip so you can check for leaks before you leave home...Check your differential fluid... carry a cell phone with you... be sure batteries on it are charged... if electrical system goes out you won't be able to use the cig lighter .... have extra fluid for trans, brakes , etc...? Checked the air in your spare tire, have everything needed to change a flat ? Always carry duct tape.... even if you are not Red Green from Canadian PBS....Drive carefully.... Greg
