On this MTH BN GP30 I painted the step rails white, added red paint to the fuel filler areas, painted the lower body frame area near the fuel filler cap a flat black and moved the horn (and painted it) to the left top of the body between the front and middle radiator fans to make it look more like the prototype. I also replaced the incandescent headlamps and amber flashing light on the cab with LEDs and had GGG up grade it PS2. In the future I plan to add the conspicuity tape striping to the lower sides.
