That's right the Steelhaven was the ship most of the 1987 toys came to Earth aboard, although comic Fortress Maximus was tall but not as tall as the cartoon version.
They did in a book called TP called "Balancing Act". I didn't like it that much because it took me (an avid comic book reader for 20 years) two reads to really understand what was happening and how it was supposed to fit in with the Cybertron cartoon. As the only Cybertron comic though it's not bad to pick up and isn't that pricey, but it has a bit of a fanfic feel to it.
