Hey guys - since we obviously have some engineers on here, has the coupler/latch issue ever been figured out? I know many pages back there was talk of contacting one of the big coupler manufacturers about it but I dont recall ever seeing a followup to that post. To me that is the single biggest flaw and/or safety issue with the Andersen design. Having the latch fail either while towing or when it comes time to just disconnect would be a major issue!
According to the VESC V-5 Regulation and the SAE J684 Standard -- the longitudinal test load for a ball and coupler is:
Class 3 -- 15,000# both forward and rearward
Class 4 -- 3 times trailer GVWR both forward and rearward
I don't know how much forward thrust against the ball will be produced by the Andersen system,
but it probably is considerably less than the VESC/SAE test specification.
