I might be misunderstanding what you are trying to do, but upload only transfers bullets from an ammo carrier (like the pallet) to a vehicle carrying a weapon that uses the ammo the carrier has. Before time starts, all of your vehicles have a full load of ammo and won't take more ammo. Even after time starts, uploading ammo off the pallet won't move or load the pallet...just ammo.

If you are trying to load the whole pallet on a vehicle, use mount. But I can't guarantee there is anything capable of carrying it in the scenario
