I have drawn up MARS One, Sci One and took a generic spacesuit from the SWDA, and I have to wholly agree, the vehicles do not have enough room for ALL that malarkey and equipment that the rulebook states, but I actually like the concepts.

If you browse around you can see more vehicles and such in the Other M20 folder, as well more sci-fi equipment in other folders.
