This is four years old, so I apologize. But with the recent update T-Series remaster I've went ahead and added the appropriate kingpin, and tag so the trailer is able to be coupled on the new T-Series. I was unfortunately not able to reply to the original mod here: https://www.beamng.com/threads/rogers-25-ton-tvt.67396/ , and credit of course goes to Neggy for the original implementation. I've made no further adjustments to this mod other than kingpin, and both axle beam springs. --- Post updated --- There are already a few threads up for legacy T-Series, however I've went ahead and adjusted the fifthwheel tags, and kinpin tags for them as well. Kingpin vertical offsets were adjusted to 0.90 from 1.10 (down) to compensate for kingpin lock depth on fifthwheel_v2 tag. There was no fifthwheel vertical adjustment for legacy t-series, modified legacy kingpin depth suits fine. The only edits have been coupler tags, and each work on both legacy and remastered. There are some other mods that could use updating on legacy files, like IYB's off-road. Also, these adjustments should work just fine for GTG's T-Series Expansion; as shown in the video.
