2021 Ram 3500 H.O.

We might be at the point where our trucks can tow more than they can safely stop. Big trucks use air brake systems which require air pressure to hold the brake shoes off the drums (or in some cases discs). When air pressure is lost buzzers sound and lights illuminate. If the pressure continues to drop a dump valve will dump the remaining pressure and the brakes will be applied by spring pressure locking all the wheels until the problem is rectified. I’m not aware of any such safety mechanism with electric brakes.
