To get the "Errand boy" trophy, you need to complete the task of Dutch, namely, to find the location of the tube. To do this, go to the cabin located East of the Pronghorn ranch in West Elizabeth. A surprise will be a meeting with a bear, which you can calm down with dynamite and continue to search for the pipe inside the hut.
Before proceeding with the search, you must first get a corresponding order from Dutch. He will give it in the camp of Arthur's gang in the second, third, or fourth Chapter. This will happen in the daytime, between 8.00 and 20.00. Find the tube before the end of the fourth Chapter.
