RE:Hino and Linamar at ACT ExpoWow another brainiac!
That reference is for a class 8 vehicle. SEA has been working with Hino on class 6 and 7 vehicles which represent the meat of the market.
While I could be mistaken, I don't believe SEA has introduced a market ready class 8 product.
Hino (Toyota) will have multiple vendors and those vendors are chosen for a number of reasons including having product that is ready for the market.
Perhaps your GWrection isn't as Huge as you would have the board think!
