We are full timers and came from PA. As you may know tire pressure does change with altitude. I doubt that you would be making the trip in one day. You should check your tire pressure before you start out every morning and at rest stops give it the kick test. When the RV sits for extended periods of time, the tires could change too Always check the pressure 1st thing in the A.M. before you drive. We came from volunteering in MA this last Summer and are now in Destin, FL. We have been here for about 3 months and both truck and RV did need air the other day.
