To buy used or new?

I'm going through this right now after researching and planning for about 4 years. Just sold my pop-up and really would prefer to buy slightly used (2-3 years old). The problem is, there seems to be a shortage of used campers in general in my area (East TN). Typically dealers have many to choose from. I don't know what is causing the drought. I may have to wait a bit and save some additional money for a new one or start entertaining used options farther away.
