YouTube is full of videos of RVers who have lost their air conditioning units, and anything else on the roof, while driving under low overpasses. To prevent this from happening to me, I had a friend help me measure all of the high points on my RV, and then purchased a sheet of plastic letters and numbers at an office-supply store. I placed the letters and numbers at the top of my windshield so that when I come to an overpass, I just look at the top of my windshield to know if I will fit. The numbers show that the top of my air conditioner is 11 feet, 1 inch, and the top of my CB antenna is 13 feet, 9 inches (when it’s up).
