Check out this conversion: https://redbarrontrucker1971.itch.io/fs25-anhydrous-ammonia-pack — Red's Modding gives proper credit to the original FS22 modders (Collins Custom Modding and loki_79). Shame ColdwaterCreekModding just took their mods without credit.
I’ve tested it and it works great! No triggers showing at the buying station, but it still fills up just fine.
