Toyotaman; by your user name I can see where your allegiances lie. I have to say that I am not a big Toyota fan or do not see where any Japanese truck that I have seen or driven is any better than any other truck. The one thing that I've noticed that all Japanese trucks have in common, especially those with "C" channel triple masts is this: Lift a full load at maximum fork height, Side shift the load and watch the mast deflection. Pretty scary to me...and I'd still like to know why most Japanese trucks need to employ an "idle up" device to keep the engine from stalling if the engines are indeed correctly sized to the truck. My guess is that the 4Y engine just might be a little too small to power a 6,000# pneumatic.
