Hmmmm. Dan, I don’t see what locates that trailing arm laterally. I see a vertical link that appears to be connected to a bellcrank. Looks sort of like an old fashioned friction damper (shock absorber). But I don’t see that that link would stop the arm from moving sideways. So I suspect that the tread was scrubbed off the tires as they were running with a lot of toe-in or toe-out. (If the trailer wasn’t noticeably moving sideways, one could suspect similar geometry on both sides…) The camber you can check by putting a level up against the tire and using a little trig to calculate the triangle. There are homebrew ways of measuring toe, but they may not tell what it’s doing on the road. If you know a good racing suspension person it might make sense to have her take a look at it.
