I was shopping for a used TT. The TT that I was looking for is around 26ft bunk house camper with or without a slide. I noticed that the cost or asking price of a 5 year old trailer was sometime too close to a brand new TT that was on sale with huge mark down like a RV show price. I almost made a mistake of buying a used one without a looking at the new one to see what kind of deal I could get. I bought my camper for 18K last Saturday, a lot of used one with similar floor plan between 8 to 10 years old have a asking price of over $10K. Many of them were in $12-15K range. So I figured that in ten years, I may loss around 6K or more. The math is much different for higher end TT. Like Mercedes, it deprecate a lot more than a Honda. My 2 cents
