The FriendG 10

To unlock this achievement you simply need to leave Trumbull County in the RV for the first time during a Breakdown game. Level one of Breakdown will start with you choosing a home base. Breakdown works in the same manner as the main game where you scavenge for resources, kill zombies, and build up your community. Early in the game you will be given a mission to locate a RV. Once you find it you will have to complete some tasks to make the RV drive-able, like repair the engine or get fuel (depending on the Breakdown level). Once the RV is ready leave Trumbull County and the achievement will be yours.

Before leaving Trumbull County in the RV, you will have to choose 5 other players to go with you on the RV, plus the character you are playing with, plus Lily for a total of 7. All other characters will be left behind. Make sure to go through all characters that are being left behind and dump all the items that they have on them into your main inventory, otherwise you will lose them. It will also add to your influence score and having that number up is always good. If you have more than 6 survivors in your community, make sure to choose the best characters such as heroes and other members with special skills to go with you on the RV. Any character with expertise in construction, medicine, or cooking is also worth bringing as it well allow you to upgrade certain facilities once you find a home base.
