I would also recommend 2 spares and installing a good TPMS system so you can monitor the temps and air pressure of your RV tires while your driving. I'd even pick up a small 12volt air comp also just in case or a 110volt if you have an onboard generator. I have a 5gal 110volt Dewalt comp I carry when we go camping or traveling, some say 2 spares and a comp is overkill but I'd rather be safe than sorry. I've had 2 flats on a tri axle toy hauler before within 50 miles of each other and its not fun but I just happened to have 2 spares. Then all new tires and wheels with TPMS system when we got home. Oh and I would also take a battery Dewalt 1/2" drive impact too! Don't forget a good jack and or Trailermate also.
