We have never believed in extended warranty's but we got one this time. Yes it was expensive but we realized there is a lot more technology in these coaches today and I have looked at the cost of replacing the items in question and the cost is huge. The warranty that we got includes the tires. We feel that it at least gives us piece of mind and we know that we will incur no expenses in the next 6 years. Yes it was probably a waste of money but we really don't know at this point. We will let you know in 6 years LOL
