Refuel (Side Mission)
Liberate Lorna's Truck Stop in Faith's territory, then talk to the starred NPC to begin this mission.
Follow your marker to Aubrey's Diner. The bow is good weapon here- it's stealthy, and it doesn't blow things up.
There are actually five hostiles here- four by the truck, and one behind the building.
Take them out, then drive back to Lorna's. There are no scripted hostile encounters.
Park in the designated spot to complete the mission.
