I'd be thrilled if the DLC's just gave you an actual safehouse to use, with safe-to-use containers and a well-rested bed. Honest Hearts' safehouse could be a park ranger station (preferably along a river), Old World Blues' safehouse would just be a small room similar to Father Elijah's room in the Abandoned BoS Bunker, and Lonesome Road's safehouse would be just like the old couple's house in Book of Eli.
