This is not directed to anyone in particular, but exploring “who” designed the new trucks is an exercise in speculation and will likely only serve to get this thread nuked. I’m only one opinion, but I don’t believe “who” even matters - just get them fixed.
On a pleasant note, I received my Vision PS-1 MoPac Eagle boxcar. The dummy coupler (remember one is an electro coupler) has a hidden tab and couples very easily to other cars from various vintages. It is also articulated. It still has plastic bolsters and side frames, but it at least functions much better that the Friendship cars. Hopefully, this is a sign of what’s to come.
