As the Chief says in Post #13...don't buy it through your dealer. It's marked up beyond how high they can count. The link below is an interesting read. Although packed with Ads and sounding like he's pumping Good Sam, it's followed by testimony and stories of actual owners. The initial warranty is sufficient. Drive it a few moths and see how comfortable you are with fixing things...you have warranty already in place at this time. Dealers know...if they don't "Sell You" at the time of delivery, the chances of you purchasing it later (especially through them) are slim to none.
