Build 3D Log Truck in .skp format #2

I am reconstructing a collision involving a log truck and trailer (NOT a stinger-steer). I have a model that can be modified to meet specs, but too large a file to attach here (Dropbox transfer - see pic of red model attached). I need a scale digital 3D model of a 3-axle Kenworth straight truck loaded with logs pulling a 3-axle full trailer loaded with logs as depicted in pic of green truck. The fence poles in my current model (red) will need to be replaced with 30-foot logs. The model must be able to articulate (pivot) at the hitch and trailer steering axle. This combination is 80 feet long with a 8 foot interval between truck and trailer. Dimensions will be 8.5 feet wide x 13 feet high. Any existing models that can be modified to meet these specifications by the modeler are fine. Component colors must be changeable. I am attaching a photo to illustrate the general configuration required.
