Another vote for not crazy. I just got my RV in December and I'm having so much fun I can hardly stand it. Oh, I guess I could have found something else to do with the money, but at the end of the road I would have had regrets. We just did a fabulous week in Massachusetts and the other day I figured out our route for our Yellowstone/Teton trip next year.
So, who's crazy? I'm not even finished with this year's trips and I'm already obsessing over details about next year. Just call me one very happy camper.
