If you are thinking about buying new be aware of a few facts:
Lemons come in two flavors.... new and used.
New warranties are only as good as the nearby dealer is willing to make them.
Buying new is fun and a lot easier but very expensive contrasted with used.
Buying used is a lot more work but will save you thousands or even tens of thousands.
New or used the internet is your friend.
If you buy a late model, lightly used RV the little things will have been fixed and anything major will be glaringly apparent.
If you buy used it will probably come with a lot of stuff, again saving you serious $$$.
In many states (Arizona being one), there is no sales tax on private party sales.
When you get free advice (like this), you get what you paid for. Good luck! :B
