Well, I just returned from a week's vacation in Florida, so I'll not be too sarcastic! I guess my 5 days in Florida qualifies me for a temporary Snow Bird status! I'm back in the snow again today! BUT, I've had no association with Arizona yet, so I can only be half-sarcastic! :B
My opinion? Go for it! Actually, if you live in a cold weather state you can still use your camper a lot (driveway camp) with no water in it. You'll have a lot of fun, and you'll learn a lot about it, especially in cold weather! And if you don't spend time in it, nothing lost. (But I bet you will).
Right now, prices are good. Last years models are going out, next years are coming in. RV shows are planned all over the country right now, so lots and lots of people are buying right now. Indianapolis is having their annual RV show in about 2 weeks. And we're buried in snow right now.
If the price is right, you have somewhere to store it, and the irons are "hot" ... go for it! If you wait, you just might talk yourself out of it later. Sometimes we have to all be a little crazy to buy a new RV. If we REALLY logically thought about what or why we do, no one would ever buy any!
