Well, I just went to look and our ball receptacle doesn't have the back structure other than the latch and a plate at the bottom below the latch. I'll have to take this up with Andersen and ask if they tested their hitch with these type of latches. Worse comes to worse we'll just be out the return postage, not good but not all bad.
I just emailed my question to Andrew with Andersen Hitches: "Our trailer outlined in an earlier email I've sent you has a hitch designed with a ball receptacle that has no structure to support forward force of the trailer other than the ball retainer latch and a moderately thin plate below the latch. My not classically engineering educated mind tells me your system pulls the trailer forward putting a good amount of pressure on this latch. Have you have tested this hitch on this type of ball receptacle?"
While composing my question I thought about the way it works. If our ball receptacle is designed to take intermittent forward force from the trailer while going down hills and initial bumps from rapid stopping I'm not sure there will be a problem. Nonetheless I will be taking special interest in the condition of the latch every time I hook up.
