Quoting Internet sources does not legitimize them. I am not saying they are all wrong, but the methodology begs for documentation and verification. Scale tickes? Independent observers? You know the routine. There is a right way to test things. I can quote ten people on the Internet that think that we did not go to the moon.
Some people sure spend a lot of time and energy with negative comments about the Andersen hitch. I can only report from personal use that the product gives me a better towing experience than the half dozen other WD hitches that I have tried over the past forty years. That may be purely subjective, but I am not saying that is what ten people say. Therein is the difference. If anyone actually wants to discuss, or even test tow with an Andersen, they can contact me. I am currently in Texas but who knows where next month?
