And sadly, you may find 80K doesn't get you a great quality new RV. Buying used is "safer" in my mind. You can buy a brand new rig and still have problems (breaking it in, poor workmanship esp in that price range etc). With a much smaller up front investment you can buy used, get the unit up to snuff as you say and have just as much fun.
We bought used and get for 28K what would be 130K new. It needed 3K worth of work to bring it up to code. It had improvements a new unit wouldn't have. We don't have to worry about small scratches or the dogs making a mess. You get the idea.
