Best time to buy a premium USED fifth wheel?

Buying new is best done at the RV show in Hershey Pa. The deal is; its a manufactures show that preview all of next year models to dealers and consumers. If you buy one of the units on show , they will forgo the transportion cost, and all dealer prep costs. Don't know the exact numbers, but talked with quite a few pepole who bought and have been repeatly told that if we buy knew, that was the place to do it. Met 1 fellow who bought an 250,000 DP and was having the dealer deliving it in the spring, until then the dealer was storing it. Fellow got into his car and drove back to Texas. Me I would of drove it home viva the northern route.
