I called Andersen MFG. The marketing guy couldn't answer some of my questions and transferred me to the company president. Here are some of the questions and answers.
Question: "If you were spending 40K on a new trailer, would you be comfortable using this hitch"?
Answer: "I wouldn't use any other hitch".
Question: Do you need to tighten / loosen the two nuts for hitch / unhitch?
Answer: Yes. First time you hitch, tighten the nuts to compress the bushing 1/4 inch. Then count the number of threads (same as counting chain links with other types of hitches) sticking out of the nut. Subsequent hitching up, you tighten to that thread position. No torque wrench needed. I mentioned marking the threads with paint or nail polish, he said "good idea, once you get it set for your trailer".
Question: Unhitch procedure?
Answer: Pretty much same as other types of hitches, tongue jack down to take off weight, loosen the nuts, and pull the pin to release the plate. No heavy bars to remove, no heavy hitch to remove, this entire set up ways about 60 lbs.
Question: How often is it necessary to replace friction material inside ball mount?
Answer: It's got a lifetime garantee, you shouldn't need to replace that.
I was told this hitch was in R&D for five years and only started marketing in August 2011. They did not want to compete with Reese and Equalizer, with a product that was similar to Reese / Equalizer design. Thus, a totally new hitch concept.
The guy was pretty convincing.
