I pulled a 40ft 5th wheel Keystone Raptor Toyhauler with my Anderson hitch. Setup in Shortbed mode. It's strong no movement. I'm totally happy with it and have no concerns or issues. It's a strong system, works great!
Please don't take this the wrong way, but...
I can walk across an interstate blindfolded and happen to not get hit by a car or truck.
About 40 years ago in my youth, I got away with driving in conditions that I should never have been behind the wheel.
The fact that I walked away unscathed from both of those situations does not make them "good", "Safe", or "recommended". If you play Russian Roulette and happen to survive, does that mean it's "safe"?
I personally think it's criminal that Anderson is not forced to disclose that their hitch SHOULD derate the payload (pin weight capacity) of ANY vehicle using them. Why? This is not my "opinion". This is fact. Anyone who understands the math behind GVWR, Payload, pin weight, etc should easily understand this.
In ALL circumstances - not even just when using the Anderson to move the trailer connection back for short bed trucks (but even MORE so then) the Anderson hitch causes downward force (load) to be distributed BEHIND THE AXLE. Whether "officially" people are required to consider this or factor it in, does not make it any less factual or true. When you use it on a short bed, it SIGNIFICANTLY alters the geometry and load.
I see people pulling way heavier trailers with 1/2 ton trucks and getting away with it. Doesn't make it safe, or right. Just like with this hitch. I sincerely hope anyone using one stays safe. However I would never, ever, ever allow anyone in my family be be near one. I'm sure there are folks here on this forum who have pulled more than I have. But I personally have hundreds of thousands of miles pulling pretty heavy. This ain't my first rodeo. There are way more examples of this hitch failing in various scenarios that just don't seem to occur with "traditional" GN or 5W hitches. Seems to me that even beyond the incredibly obvious physics problems, that would be enough. No matter how much todays world seems to demand it, "easy" don't make it "right".
