ACME vs American/Stehl - turning explanations needed

The big advantage Acme has, is there is no danger of the fenders hitting the vehicle in the turns......because nothing turns.

If you want the very best dolly on the market, get a Demco. It mite still be the only dolly that uses king pin steering like a motorhome. This design also lessens the chance of fender contact in the turns. They twist a little, but not near the movement of a turntable dolly.
