Originally from the Hub, Trent moved to the Mojave Wasteland because of the Thaler Act. He has trouble meeting his crop quota and complains that there isn't enough water. He grows maize and tobacco. Investigation of this issue reveals that the water is being illegally diverted to Westside.
If the Courier resolves the issue in favor of Tom Anderson, the person responsible for the water being diverted, Trent will mention that he's going back to California since he has no way to meet his quota. However, if you report and kill Anderson, his quota will be accomplished more than he thought, and will offer you some surplus of tobbaco and maize.
