Both have the high rider chassis of the 4x4 model.
The G has almost all the features and the look of the 4x4 model but without the 4x4 system. The only apparent difference is the lack of a hood scoop (different engine) and different wheel design. Otherwise, it's just like the top line 4x4 model.
The E is bare. Rides on steel rims, no fender flares, etc. It looks like the 4x4 trucks issued to the Red Cross but without a 4x4 drivetrain.
Detailed specs can be seen at the local Toyota website.
The Hilux J and cab chassis still ride on the standard height 4x2 chassis.
