MT? Truggy? Buggy?

[E-Revonut]

Sorry to sound like a complete idiot but for the life of me I can't figure out what distinguishes a truggy from a MT. The differences between buggy and MT are pretty obvious. I have a T-maxx that is obviously a MT but I also have a revo and an e-revo that I wouldn't really classify as MTs. They have much lower cg and handle way better but they still take to the big air jumps well with their big travel. Basically what makes a truggy a truggy?
