I think it would be great if prime had his trailer in at least one scene in t2. Just here me out for a sec. We all know that prime pulled his trailer eveywhere he went in the cartoon and fair enough it not being in the first one as it would look silly when he transformed and his trailer just either got in the way or disappeared. I think that prime should tow his trailer in the t2 and have it open up as per the cartoon and actually become the autobots base or part of it. Then it just stays as the base and doesn't go anywhere. Also roller has to make an appearance as well just for a nod to the fans.
