I was looking at the FansProject G3 Trailer and the Best Toys Mobile Command Base trailer and it occurred to me to wonder if you could put the two together. You know, hook the G3 up to Prime and then attach the Mobile Command Base trailer instead of the D.I.A. Commander trailer. I know no one has the G3 trailer yet and probably can't answer the question with any certainty. I would be interesting though. Or heck, it would interesting to see if you could make Prime drag all three of them around.
