Hi;
The sad part? When AMT and ERTL brought out the big rigs and some offshoots they completely forgot to include one of the most ubiquitus vehicles on the American Road.
I have seen a few in 1/24-1/25 but they are Oil company or other company's collectibles I did buy a vehicle that way.It was an oil company supervisor's R.V( Winnebago) and converted it to a true scale model.
I would NOT do that again.
