very nice trucks, it looks like a older Iveco prime mover that we have at work (im a truck driver). I think it needs a gap between the cab and body for a reefer unit.
great model it looks like a scania type 4 with a aerial pack. We have several in Victoria, Australia. There is also a few in New Zealand and most are based on Scania chassies. I agree with the person who said about the flat instead of bubbled pieces on the side of the cab.
