That's a pretty good point, zombie84! I don't think even the Marvel comics in between films ever specified the location of Jabba's base of operations. And Lucasfilm was keeping an eye on those if only to make sure they didn't unintentionally do a plotline similar to the sequels.
The story in the Marvel comics was the search for Solo. They were looking for Han because they didn't know where he was.
