Electric Slide Outs: The electric slide out system uses a motor that drives a gear system. These types of systems are generally used on smaller slid outs. Electric slide out system usually work very well as long as they have been designed properly and are not overloaded.

However, just like the hydraulic system they are prone to several vulnerabilities. For example, the motor or gearbox can go bad, The drive pins can shear and the motor can draw excessive amperage if it encounter any resistance in the slide out. This can cause damage to the motor or slide out and will probably trip your breakers.
