OK.
Here is the Racer's Digest Condensed Version.
Cabover trucks became prevalent in North America as the need to haul more freight on tractor-trailer combinations increased, but the legal length did not. With the cab "over" the engine the length of the tractor chassis could be kept at a minimum, thereby allowing for the maximum trailer length possible, and allowing the maximum load carrying area.
As more states began revising combination vehicle length laws, and also allowing higher combination vehicle gross weights, the need to make the tractor design as compact as possible diminished. Cabs began to "move" back toward the center of the chassis, sleepers also moved reward, and even began to grow in size, with added features not possible or practical in the cabover designs.
Conventional cab designs offer a better ride, better ergonomics, allow for better driver comfort and ergonomics, and allow for more ready access to the engine for maintenance and repair. Conventional cabs also offer a more quiet environment for the driver, and less heat is transmitted into the cab.
The reason that Europe still predominately has cabover trucks is that the roads in the cities and towns were designed long before the advent of motor driven transportation, and centuries old buildings border directly upon those roads. As such trucks and tractor-trailer combinations have to be designed with the limited room to maneuver in mind.
