The question has a simple answer, weight. These large slide outs are heavy, electric slide-out motors produce, at best, 900# of thrust. In this application the hydraulic system can produce 3000# of thrust. For many years the manufacturers compensated the lack of power by using gearboxes that were very slow. Have you ever had to look at the landing gear to see if it was actually moving when you pushed the button because it was moving so slow?
