Not sure what the purpose of the post was but I think the mindset with most anything mechanical is that the "little woman" can't comprehend the complexity, can't make decisions on her own and has no money of her own. Salesmen see no reason to "waste" their time.
On the Thor products... think long & hard and really LOOK at some in 3D. There are a lot of complaints about quality in Thor products and the one THOR motor home we considered had a multitude of fit & finish issues.
Compare your RV to similar ones being sold on the online sales sites to get an idea of pricing. You will not get nearly the price from a dealer as you can selling it yourself but that presents it's own set of problems. Run a NADA report on your RV and figure the low end retail is about what it should be priced.
Good luck!
