Years ago I was told that the NADA guide prices are based on a fixed depreciation scale for all RV's. It uses the same depreciation for all manufactures and models, ignoring the fact that certain makes retain value far better than others.
I learned that when I owned a Lazy Daze class C, a brand that retained its value much better than most. There was a big difference between the book value on the Lazy Daze in the NADA versus KBB, supposedly based on sales.
I am not saying that is true with Alpine Coaches. Just something to keep in mind.
