Pontooning greatly increases things like accident rates, driver stress (which leads to more accidents and requires higher wages), and reduces flexibility. The fuel savings may be lower than the increased costs of insurance. It seems to me that the same factors which would favor pontooning would also favor rail transport, which is much cheaper and fuel-efficient than trucking can ever be, but has problems dealing with small loads.
Platooning does reduce flexibility to a certain degree, but rail decreases that flexibility by another order of magnitude, as laying down new tracks even to a purely industrial property neighbouring a railway line is a very large hurdle.
