This trailer has modified realistic physical parameters based on GAINT’s official Krampe SKS30/1050.
Specifically, I moved the trailer’s center of mass from the rear to the middle. The tire friction scale is set to 1. Bulk materials have an independent center of mass whose height varies with the load. In other words, turning at high speed with a full bag in bulk will cause the trailer to flip over.
Besides, I added collision to bulk, remade the reflective strip, replaced the hose model, removed the mass limit, and added color configuration and suspension animation. The first axle is liftable. This trailer is now more suitable for the tractor with the lower saddle.
