Basically light duty trucks take an extra 10-30 feet stopping from 60 MPH. This is dwarfed by distance travelled during reaction time. In the 1960's sedans were in the ~150 ft range for 60-0, about what modern pickups achieve. Heavier vehicles have more kinetic energy at the same speed but the braking force for all vehicles is proportional to mass and friction with the road surface which depends on tire quality and road material, and since acceleration is proportional to mass from a given force the deceleration from braking is basically the same at any mass with equivalent tires and road surface.
