Did I just buy a 5th wheel?!?!?! What did I get into?

Most salesmen don't know what they are talking about when it comes to "towing", or will outright lie. Our first trip to a dealer we were told "you can tow anything on our lot", and we were shopping for a 5th wheel. They never mentioned payload, but we had done a little research for ourselves. We started with a 250 but were too close to max payload with our 32'. Much better with current set up, fiver is 35'.
