The refueling stations for vertibirds are actually not necessary, since the mod seems to think that anywhere you land is one. Bit of a mistake on his part, but whatever, makes moving them to DC easy :) If you want one there is a full height copy of the tower in the test cell, just copy and place.
Markers can be set visible by hitting M, or going to the View menu, show/hide window, and click the Show Markers box.
For Cars there is also a copy of the refueling station in the test cell in that plugin. Just copy/paste it into the world as well, ensure that you have markers enabled when doing this. The refueling stations also need navmesh to work properly, which will require some work, as the exterior cells have special needs when navmeshing.
