Jeff, it's been a while since I bought and installed these, so I'm working from memory (ha!) here. The first pack is the textures and CR2 for the outer body. You get 3 different texture sets, all of which are compatible with V1/V2. This pack can be used as a standalone. The next ones are where it gets complicated. The add on packs require you to remap V1/2 and save the result as a different named OBJ. This will take the mechanical inner parts. Each of the add on packs has a texture file for the inner, and a transmap to work on the outer tex. The outer body uses the same textures as the first pack, ie, it's totally V1/2 compatible. So, the short answer is, yes, you'll get the basics if you buy the first pack, but you won't get the inner body or any of the mechanical bits. Hope that's helped.
