I think its fine thw way it is really. The tacomas can be grouped together with the runners and all FJ's. The T100/Tundra forum here is the only one I see that ever gets much traffic, all the other ones are often ignored.

What you could do that would unclutter the entire forum is to make a forum then have subforums inside it. So you could take other forums and consolidate them even further.
