The modification is a conversion from SnowRuiner...  The mod has:
– various animation
– your sounds
– your textures
– your addon (only saddle)
– your tuning parts
– compatible with sr trailers, semitrailers, addons from various authors
I recommend install the latest version of spintiersmod for a comfortable game.
tested on mudrunner v22.03.19 + xbox one gamepad. (keyboard not tested)
