Does this used C look like a decent deal

Something to consider. This couple bought this RV new 8 months ago. If they financed it, then they are probably massively underwater. As I posted elsewhere recently, I'm convinced that one of the reasons why RV sellers are offering 15+ year terms on RV loans is not only does it make it so that more people can afford them, but it totally destroys the used RV market. No one can afford to sell them until they are 10+ years old, by which time nobody wants them as they are starting to fall apart if not stored well. So it becomes very hard to find a newer RV sold at a "reasonable" price because everyone needs to make the loan payoff amount, which is going to be way more than the actual value.

Unless you find the rare unit where the buyers paid cash in full or a large down payment and then decided to sell while the unit was pretty new, nobody can afford to sell their young financed RVs.
