SAS is SAS, add it and it is the same. GOAT mode changes with models
OBX has base offroad but 18" wheels and Sport mode.
Base/BB have mostly standard off road packages and 32s
BD gets chunky 32s, steel bumpers, bash plates, rear locker, and Sport mode
BL is almost SAS with all BD + front locker, bilstein, 33s, and Baja mode
WT/FE are SAS
So offroad is in that order. All are more then capable. May have missed something but that is off the top of my head...
