I need a specific firetruck drawn in SketchUp

I need a firetruck drawn up in SketchUp. The level of detail can be minimal but the shape and basic size/structure must be accurate. There are quite a few trucks already drawn in the 3d warehouse, I just need what is already available in the warehouse edited to match the attached drawings.

The most important shape is the cab of the truck, the shape of the ladder, and the overall size. This should be one hour or less of work. I am going to be placing light fixtures all around the truck and measuring light output, so the most important thing is basic shape and overall size. I do not care about small detail.
