Planning is key to making a long trip stress free. Plan your stops in advance and not when you urgently need them for fuel. Know the maximum distance you want to travel on a tank of fuel. I use Google Earth to scope out all potential stops for fuel, food and breaks. Sometimes you will not always need the huge truck stops for accessibility of a larger TT. I also pre program the GPS with these stops which I call my waypoints for the trip. Take your time at the pumps. Don't be a jerk and by loitering around for an hour but use the time wisely. DW usually goes into the restroom while I pump fuel, then she stays with the rig while I do the same, which is always faster, Find a plan that works for you and be safe.
