1.toggle on packet canceller on kami blue with player packets + vehicle move on
2.toggle on auto remount for donkey with max range 0 random
3. go down the minecarts until u reach the end
4.press shift to get off the minecart and the auto remount should get u on the donkey almost instantly if u don't get on the donkey hop on the minecart and press shift again.
5. after u got on the donkey take the stuff out(make sure u don't close the inventory while u are rendering another donkey in the chunks this cause u to fail the dupe).
6.hop on a minecart and press shift again u should be on your donkey and be able to dupe.
7.repeat steps 5 and 6.
edit:
the idea here was to use the client to interact with the donkey by some kind of module because of rending issues where the donkey would actually be there server side in your chunk but you couldn't see it which is why you cannot interact with it, slowing down the dupe.
