"Blow out tires"!!! IMHO another major issue is the age of the tires. Personally I drive with 4 yr. old tires with my Good Sam sitting on my dash board:) After 5 years I throw the tires away and buy some new tires. Yes, I know there are many individual stories of RVers who have tire experiences that are different than mine. I really try to avoid having to spend 2 to 3 hrs. waiting for EMRS to come and change the tire or having to pay $$$ to repair the damage to the RV after having a blow out or tire separation :(:(
