I have been considering purchasing an extended warranty for the 07 Georgetown we purchased a year ago. The cost of the warranty is $1650 for a five year warranty with only a $100 deductible. The only problem that we saw is that in California they don't allow arbitration if there is any kind of dispute on the claim. I think the cost is pretty good considering when we purchased the RV, the dealer wanted to charge a lot more for a shorter warranty period. The warranty we are looking at is through GoRV. We looked at Good Sam too but this one is cheaper and with a smaller deductible.
Please let me know if you have any thoughts on this or experience that might be helpful.
