If you like the unit go in and offer the dealer $11500. OUT THE DOOR and with a RVers starter kit included. OUT THE DOOR IS IMPORTANT because some dealers will put all sorts of BS fees onto the sales price. NOTHING IS MANDATORY EXCEPT DMV FEES. Remember the salesman is not your friend. You are the way he feeds his family nothing more.
When you go to pick up unit do a thorough inspection Before paying for the rig test all systems and check for any leaks from rain. Do not give them the money unntil it al works
