The Kenworth is a K100E, with a tricked out 8V92 Detroit Diesel. The colors are inspired by the rig of Northrop Enterprises, one of the rare true custom K100's running.
The truck has working doors, tiltable cab and color trimmed interior. Many parts are chromed with 'plating on plastics' technology (no paint).
The trailer is a Walker, in traditional setup. The body consists of Lego Technic panels which are chromed the same way.
And a 'ghostview' made in Photoshop to show the engine and fittings:
