I am glad the tools are getting some use. Been really busy with real life stuff, so I never got around to figuring out how vehicles work. For the more advance users of Blender, you can import what I call "metadata" by checking a box in the importer. The data will show up in the object tab, under "Custom Properties." You can tweak things and when exporting the model also export the metadata. For example, I deleted the UAZ's canvas cover and had a fully working vehicle. The metadata could also be edited and exported, facilitating reverse engineering of its meaning.
