Wondering if anyone can help me with the purchasing of a new camper. I have two that I am looking at but wanted somone else's thoughts. 2004 Prowler quad bunks in back also has a slide out. Dealer wants 14,500. Another dealer has a 2007 brand new Springdale with the same layout quad bunks and slideout. for 15,000. Any reason why I shouldn't purchase the brand new one for 500 more?
