For my autoloader to work you must now go grab Achimobil's PALLET AUTOLOAD SPECIALIZATION V1.2.0.0 mod from here.
Special thank you to him for working with me to make our autoload mods compatible once again, adjusting his scripting to allow the bale loading to continue to work on this trailer, as well as all the hard work he puts into his mods for us in the FS Community!
