Well yes, I did use multiple textures...but the main hull texture you see in the pics (the light gray paneled text over the entire hull) is a single 4k map. My UVs are properly laid out, but they certainly go over the 0 to 1 UV space. I'd take a snapshot for you, but Maya only snaps in the 0 to 1 and not outside it.

Is this bad? If so, why? I haven't run into any problems so far.
