How do you define a Monster Truck?

[TexasSP]

These should be the base rules in my opinion. I also think there should be a freestyle competition where anything goes though.

MT:

High ground clearance
6" or larger tires/No foams
Chassis built above diffs
Transmission
Truck or SUV body
No Sway bars
No wing
Minimum 12" Wheelbase

Truggy:

Chassis below diffs
5.5" or larger tires/foams acceptable
Center Diff/No tranny
Lower ground clearance
Truck or SUV body
Wings acceptable
Sway bars acceptable
