Apart from running the biggest shop downtown, he is also head of the Stockmen's Association. He is a stocky fellow with a constantly flushed face and shock of thin blond hair. He walks with a slight limp. Duppo has a friendly demeanor, and will offer a job to anyone willing to work hard in the brahmin driving business.
Additionally, he has an illegal side venture: a casino in the back of his shop. He operates it right under the nose of the NCR police force (across the street from the station).
Complete brahmin drive: The Chosen One must have completed at least one caravan escort in order to gain access to the casino. After doing so, they should ask if there are any faster ways of earning money there. Duppo will give the password to the door in return.
