Little tip looting destroyed convoy just run along the left side of the map and kill and loot the very top of it only.. if you have the weapons then go loot the bottom of it but the only thing worth it that is there sometimes is the finger that you get off the dead body of the soldier.. You can use the finger to unlock the secret room in bunker alpha lobby for a glock and copper bar
I don’t need most of stuff there so when I go I look to see which one it is, Zs I just leave and raiders I just walk up and check the dead guy for the finger
