Building Tip - temporarily installed four 2x2 DBG inverted tiles and one 4x6 Yellow studs on edge tile to stabilize the model during assembly. They are leftovers from the 60150 kit and can be easily removed before installing the wheels and tires.
Interior mod - front view. My kit was a hand me down and did not come with all the extra parts. If I had all the extras, I would have made the left side of the interior look the same as the right side.
