The factory warranty on my 2014 Lifestyle runs out the end of April. I am getting a 5 year warranty through Wholesale Warranties. Got a quote of $2,900 for a 5 year warranty. with $100 deductible. I have used them before and for me it was money well spent, in fact it saved me money on repairs when I had it. When I purchased the 2014 Lifestyle I cancelled the policy with Wholesale Warranties and got a prorated amount back for over $1,000. Policy works out to $590 a year.
Got a quote from Good Sam and they wanted $1,600 a year.
The bottom line is to shop around and then do what you are comfortable with.
