You might want to take a look at RV Classifieds to see what people are getting rid of. I haven't looked at the "Pickups and Vans" category, but in the Travel Trailer section there are about as many new units advertised as old ones.

Not suggesting these are good guys to deal with, as I don't know that much about the site; but they do give a good "birdseye" of brands and models in the market.
