Many good thoughts via others, so here is my 2 cents worth.
Many of the entry level Travel Trailers are built poorly, and simply do not hold up. So good price or not, not a good value.
The average RVer uses the camper 3-5 times a year, generally for a few days at a time, and one 2 week stay (this is based on industry studies)
Since people can not easily vacation abroad, they still want to get out and explore, so some are choosing to try RVing. Some will like it, many will do it until other options are available, a lot like boating.
Financing an RV will prove challenging for most, as it is one of the most risky loans a bank can make, as it is to finance a "toy", and when times get tough, "toys" are one of the first things to go.
To to buy now or wait. There will be many that don't like the RV that they choose, and those will be back on the market quickly. However, most will be stuck in a financial quagmire. They will owe more than its worth, and can not afford to sell it. So if you can find one at a better than average price, consider it, but buy what will make you happy for 5-10 years, as non come cheap enough to throw away due to impulse buy.
Also, if your looking at travel trailers,
Fiberglass is better, but twice the price.
