What are good quality travel trailers but cheap in price?

Used ones, never ever buy new. Camper trailers typically lose 1/3 their value when you drive them off the lot. I just recently acquired a used Kit trailer 1993 with a NADA (the blue book for campers) value of $10,000. for a low $3500. the market for used trailers is the same as it is for regular housing, a buyers market. Look for brand names where the company is still in business as many have folded in the last few years. Some that still hold their value even though they may be out of business are National, Thor, Jayco, Kit to name a few.
