Looking for alittle help on what I've acquired

Thanks for all the responses. I was guessing class A. I did look up price on NADA, but also saw the pictured one above advertised for $19k. It does seem rare to find these units, so that is why I wasn't sure of value. I do appreciate all the input.

I haven't figured out how to upload pictures yet, but ours is the blue and white. Very nice looking. Thanks again.
