So we found the perfect one on, of all places, Ebay! And oddly enough - we won it.
The down side of the transaction - we're in the Chicago area and the RV was in New Hampshire. A week ago Saturday I flew into Boston, the seller picked me up at Logan airport, and took me to the RV. He gave me a quick introduction to the workings of the machine (no, I'd never driven one before), took his check, and took off. Leaving me alone at the top of a mountain with a mountainous vehicle.
It wasn't until a couple of days before I left that a few people mentioned that I was "intrepid" and "brave" for flying across the country to pick up an RV and drive it back. No one bothered to say anything before we bought it. Thanks, guys!
I'll let you in on the secret now. It was fun!
