Why not buy used? Its evident the best RV to buy is a used one. That being said I suggest a floor model returned from one, or better yet multiple RV shows. Nothing could be better than a rig that has had at least 10000 people going through it in the course of 6 or 7 days.
I was at the local dealer mulling around and pulled open a kitchen drawer to find a used diaper......whew, a little ripe too. I told him he had a surprise out in that unit LOL. He said they just brought that one back from the Pittsburgh RV show, and is nothing they had not seen before.
