In the actual mods folder, there are two parts to it - the maps, and then the actual mod. Move the actual mod form that folder to the Overlays folder. The maps folder is strictly optional, if you want to have the vehicles, add them in (although you'll have to overwrite the vanilla maps for that, which could cause some problems later on).
I haven't looked into how the maps mod has been done in this case, but I'd believe RWR should be able to handle most of that without having the player to overwrite vanilla maps or anything.
E.g. you can just have them in another package, it shouldn't matter that there are two map1's in the space, and you see the package name in the map config menu. With this approach, the player still needs to specifically activate the overlay in the menu for the particular package+map.
Or, since 0.98.4, you could have the package+map specific modifications in the overlay itself. E.g. single overlay can be made to have my_overlay/packages/vanilla/maps/map2/object.svg kind of structure to have that stuff overloaded for vanilla+map2 specifically when the overlay is enabled in the map config menu for map2. I haven't tested it extensively, so if you end up trying to arrange things that way, just let me know if you run into issues.
