I will suggest to you that there are some used RVs that are in good shape and reasonably priced. But, they aren't the norm. When we sold our motorhome, which was 26 years old when we sold it, we were highly motivated to get a travel trailer fast. But, I had been looking for months. In those months I saw one travel trailer that was what we wanted and reasonably priced. It had a brand new rubber roof, and not the roll on kind, the sheet of rubber kind. It was gone in three days. At our age we intend to keep this new one till we can't tow anymore. Then we'll keep it at the beach till we are too old to even do that anymore.
Anyway, when I do the cost benefit analysis a new unit just makes sense for us. If we were young, energetic and just starting out I would totally buy a used one. Heck, we had a few and enjoyed them all. But, I made a metric ton of repairs over the years. For a young and enthusiastic couple repairs are fun. For an aging tired old man they are no longer fun. We bought a 1977 Hippie van with new carpet, roof to floor, in 1987. Over the months that followed we had some awesome fun working on it and camping in it. After that we bought a used cab-over camper from a man that was sick with cancer. It was a little neglected but, no water damage. That was a lot of fun. Then we bought a nearly new travel trailer that had rolled into a ditch and was sold for salvage. The basic repairs were made and we did the rest. That thing was really great fun and we sold it for what we had in it four years later. After that we rode motorcycles for a few years till my wife got sick. We bought the class A motorhome and kept it the longest. I worked on it what seemed like almost constantly. It was dry and everything worked. But, with the whole self contained thing it was a lot to keep up. At this juncture I'll probably not get another motorhome unless our live radically change.
Anyway, used is OK but, lots of work if you're a bit of a perfectionist.
