JMHO, dealer probably figured you knew too much about RVs and he wanted bigger profits on it. Most liiely didn't have anything to do with your trade. I have walked into dealers that listed their RVs at MSRP. Tried to tell me they only made a couple thousand on an RV and if they took a trade wouldn't make any money except on service later. When they start lying I move on. However, A local dealer here doesn't deal on RVs but he has a great service department and he is honest. I still go for service.
An attorney told me one time, if you ask questions you know the answer to you will find out very quickly about individual honesty.
