I didn't look on the frame to see if the serial plate matched what was stamped. The rest of the truck does match the 5 series books though so I would assume it is correct. I dont think this is a grey market unit, in fact, our local dealer was the selling dealer of the unit as they install a metal dealer tag on the hood beside the data plate. All of my manuals show a simple orbitrol and steer cylinder setup on this truck just like any other fork lift. This is my 23rd year in the business and I've never seen this system on any Toyota I've ever worked on. Very strange to say the least.
