Obviously, you should buy New...how else will there be a selection in 5yrs at half the price available on the used market?
Seriously, beyond the new car smell (that's typically formaldehyde and petroleum distillates by the way) about the only reason I can see to buy new is if there is a particular model or layout you simply can't find used.
Warranty: I've known lots of people who have gotten new rigs and lose weeks or even months the first year waiting on warranty work. In PA, that means you can easily lose the summer and have a 1 yr old used unit before you have all the bugs worked out. Plus since you are loss not a profit, don't expect them to trip over themselves to get it done quickly. If you buy used and need some work, they do it in a timely manner or you move on to another repair place.
The tougher question is how old to buy. I would say the typical RV lasts 20-25yrs but if you keep it leak free and maintain it, there is no reason you can't get 40-50yrs but at some point it's cheaper to buy a newer unit than repair things.
- On a tight budget, you can get a 15-20yr old special for a grand or two that is functional if ugly and needs a fair bit of maintenance work (assuming you are a DIY kind of guy)
- We shoot for 7-10yrs. A lot of RV's get used less than 3-4 weeks per year, so as long as it's dry, it's almost like new but for a fraction of the price.
- Newer (2-5yrs) gets you a little of that new car smell but with maybe a 20-30% savings and the original owner probably already did all the warranty fixes.
