As implied, the cabin serves as Catalina's hiding place and base of operation from which she goes on a robbery spree targeting surrounding businesses in Red County following "King in Exile". The cabin thus serves as a starting point for all these missions, and also acts as a save point after "King in Exile". The save point icon is located on the east side of the cabin.
In addition to the hubcap and pelt-adorned design of the cabin, the surrounding area is also littered with other oddities. Directly west of the cabin is a series of three makeshift graves and a shovel pickup, which implies Catalina had preceding associates who either died by her hands or not. A Buffalo also spawns on the east side of the cabin, and a rusted out Walton wreck can be found directly southwest of the building.
