ok, so the king hauler finally has a reduction box, 4:1 fitted.
problem was when hauling a heavy load I had no steering, it was suggested that I make a dolly trailer, had a spare flat deck doing nothing .
end result after 40 minutes is an average looking dolly, but I have steering.
will clean it up and paint, I can now haul the excavator and loader no worries.
sorry about the photo , its late and dark here.
