<font color="blue"> does he plan on using some kind of electric defroster?

Yes. Since the pictures were taken he has installed a small electric heater on the ceiling that blows down the front windshield. The BX is designed with the engine mounted in reverse. The cooling fan draws in air through a screen below the steering wheel, in front of the operators legs.
With the cab mounted there is a nice flow of fresh air that gets drawn through the crevices....which I think will aid in keeping the windows clear in the winter.
