The trailers previously served as the residences of Nipton settlers before the arrival of the Legion.
This small trailer park surrounded by a broken chain link fence is found behind a few Nipton houses on the southern side of town. The location's name appears on the sign above the entryway. A corpse of a wastelander with a laser rifle can be found here, as well as an ash pile containing the remains of a recruit legionary. Bark scorpions will attack the player character upon entrance to the trailer park.
The Good Luck trailer park appears only in Fallout: New Vegas.
