I modded the 82studios box trailer mod and made a variant to load cotton bales (up to 20million liters in unreal capacity) and the same for a wood loading one. It was an interesting challenge making it work.
My most recent victory is a modded CaseiH cotton harvester that can have the option of a 25m or 50m wide harvest swath, custom bale size, and faster unload animation.
I don't try to put them on the mod-hub because they're edits of existing mods and the authors of the original mods should get all the credit for making the mod itself. I only come in after and tweak it. But there's a link to my google drive that has them all pinned on my discord server.
