Well guys. I did experiment with a steerable trailer. I it didn't work, i fact is seemed to make the trailer go unstable (sort of spin out upon entering a curve). I played with several different configurations for the steering and then gave up for the time being: I think I might know how to make it work, maybe, but I also realized that if I could ever get it to work it was going to take a lot of time to get it perfectly, whereas added 1 inch to the inside of a curve is something I know will fix any problem. Besides, this looks very realistic, because it is how real big-rig trailers follow their tractor.I mentioned that on a thread where Lee was running a big rig on the city street, but since the work is already done to make the country road accommodate semi trucks, I don’t think steerable rear wheels is happening.
