Well yes and no... I mean an 11" wheelbase is solidly in the on-road touring car dimensions. 12.8" is longer than some 1:10th scale monster truck wheelbases.
Put another way, this body would probably fit on a Traxxas E-maxx/Summit quite well, but would swamp the 4tec 2.0.
Still... that does mean any large scale or monster truck body should fit on it quite well
