Just a comment about purchasing an RV from shows, or anywhere for that matter.
You really need a chance to check out everything in the RV you wish to purchase before signing any contract. Not likely to happen at any show.
RV's are delivered with some defects from manufactures. They might be damaged when shipped to a show, or later when shipped to a dealer for delivery. As most of us on "Open Roads" already know it is much better to get everything fixed and working before you sign the contract and make it yours.
Once it is yours the dealer has no incentive to get all things fixed under "warranty" work. With the economy picking up most dealer service departments are loaded with RV's requiring service this year and they are careful in how many people are hired for the additional load.
They will always try to accommodate their loyal customer base quickly which means newcomers may take longer to get serviced. Getting parts for repairs takes longer this year since manufacturers are experiencing unexpected demand.
