As an ME, I assume that a product that is rated has gone through testing. I have not done any towing to speak of though which is why I posted the topic. I appreciate informed opinions with real world experience to back it up. The dealerships may have both, but they come across as tools of TL or whoever else pays the bills making them tough to trust. The only thing that is a given is that the mfg installs a hitch and rates it at some load. If I don't exceed that I should be good. If not, they would be sued and out of business.
