depends on what you want and price tag. New RVs your the one eating a huge depreication bill. Last year I bought a used 37 foot challenger that had an MSRP of 52 and I bought it for 18k. so pretty much lost 60% in 5 years, although I got a steal, and most are priced around 25k. Thing with used is they can get beat, they dont make trailers like they used and things go bad quick. But then tons of people buy trailers and never use them, my still had stickers on the sinks and plastic on some of the furniture. A RV is something unless I got a killer steal would probably never buy new. Used trailers can be found that are barely used or well kept all the time.
