This mod adds a network of travel caravans to the wasteland to connect the major settlements. The normal fast travel system is still available, however this mod caters to those who prefer to make their trips between major areas slightly more immersive. Travel service is relatively cheap, and the caravans are well protected. Each operator is in or near the main area of the settlement they serve and has one pack brahmin and one normal brahmin. So they should be easy enough to find.
The system behaves more or less the same way the Stilt Striders in Morrowind did. You pay the operator and they take you to the destination you specify. No operator serves all destinations, so you will need to know which stops you need to make in between on the way to where you're going. Time will pass as though you used fast travel and should be fairly close to the actual game time fast travel would have used up.
Installation
Place the Wasteland Travel Caravans.esp into your Data folder with your other mods.
Activate using either FOMM or the game's stock launcher.
Load Order
Load order should not matter too much. All of the content added is new.
Compatibility
Due to proximity with the major settlements, it is possible that anything expanding on them will interfere with the placements of the travel operators. I have tried to minimize their footprints as much as possible.
Placement of the operators in Rivet City and Megaton took Broken Steel into account, so there should be no problems with any of the official DLCs.
This mod makes no edits to landscape or navmeshes, so there should be no major disruptions to any of the pathfinding.
This mod was created using GECK 1.5 and may not work properly on games that are using older patch versions.
