The local family owned RV business is pretty good. He didn't ask about payload, but was very interested in towing capacity of my TV. I told him what I was willing to tow, which was 80% of my capacity. He was telling me that he had a guy decide to buy a 4500lbs trailer with a TV rated at 3000lbs, and that he did his best to convince the customer otherwise. The dealer actually has a liability waiver form stating that the dealer advised not to use a TV with a trailer that exceeds the capacity of the TV.
