Most expensive way to buy anything is twice, in my opinion. If it is what you want, ( size and floor plan) then could be a great deal. If not and you end up getting rid of it in a couple of years, you may not come out too well.
Other thing, I notice is, it has no slide. Some folks don't want a slide, but I think they are in the minority. That can make it harder to sell. ( we have a 2001, 239 coachman, I would not want one in that size without a slide) Although I love the small MH length, of ours
Other thing to think about, rather than depreciation, is the concept of usage. If you are going to use it, and enjoy it. Then you will get your money out of in fun and enjoyment. Reguardless of the depreciation curve.
