Working long shifts as an account manager to provide for his wife and daughter, Hostetler is involved in negotiations on a daily basis and cares about his employer. He is also an associate of the Great Khans, and distributes chems for them in the Outer Vegas area.
“Alice McLafferty runs the New Vegas operations from here with a stern countenance. She can be hit up for work, or more information about the history of this company. Also in the office is Don Hostetler, but he doesn’t have much to say (unless you have a Chem delivery from Jack and Diane). You can take your life in your hands (and your Infamy levels to new heights) by killing Alice for some Caps.”— Fallout: New Vegas Official Game Guide Game of the Year Edition p. 306
↑Courier: "You mentioned your husband works for the caravans?" Mrs. Hostetler: "Yes, he's an account manager for the Crimson Caravan Company. He works such long ours to provide for our daughter and me. You should speak to him if you get the chance - he's always saying how badly understaffed they are." (Mrs. Hostetler's dialogue)
↑Courier: "They care for you, in their own way." Alice Hostetler: "Do they? Look at my Mother, all she cares for is a patch of bare dirt where nothing green will ever grow to feed us. My Father? A trading business that he'll never own, risking his neck every day against Wastelanders and cut-throat 'merchants.' And I'm supposed to be part of those dreams? What about my dreams, stranger? What about me? " (Alice Hostetler's dialogue)
↑Courier: "Sure, what have you got?" Diane: "With Anders out of commission for so long, we're shorthanded on runners, and some backlogs have piled up. We've got an associate in the Crimson Caravan Trading Company who distributes for us in Outer Vegas. He's been after us for a new shipment." Courier: "Sure, I'll do it." Diane: "Great. Here's the package - your contact is Don Hostetler at the Crimson Caravan. Come back and see me when you're done." (Diane's dialogue)
↑Courier: "I've got a package here from your friends Jack and Diane." Don Hostetler: "Huh? Oh! Oh, right. Yeah. I'll take that. You should go now, before you draw any attention." (Don Hostetler's dialogue)
