The Nash residence, home to Johnson and Ruby Nash, is a storefront that doubles as a house in the town of Primm. It also serves as the sole location of the Mojave Express throughout the Mojave Wasteland.
The building is located across the street from the Bison Steve Hotel and the Vikki and Vance Casino, and has a prominent business sign situated atop the roof, overlooking the main street. Prior to completing the quest My Kind of Town, the building will be abandoned.
Once the player character completes the quest and the townsfolk vacate the casino, Johnson and Ruby Nash will return to live in the building. Johnson Nash buys and sells equipment and Ruby Nash will provide the Courier with a casserole in exchange for one radscorpion poison gland.
The Nash Residence appears only in Fallout: New Vegas.
