See what your lhs supports better. I own a Revo and a Savage X SS and both are great trucks! you won't be disspointed with either truck.
I've never owned a MGT but have worked on a couple of them,never played with the suspension either but the Revo does have more ground clearence then my Savage. The Revo has more adjustibility the any other MT out there.
Both Trucks at suspension fully extended (Revo has Long Travel kit on it).
