What are RV Slide-Outs?
RV slide-outs, also known simply as “slides,” are movable sections of a camper that can extend or retract to create additional living space inside the vehicle. These sections, usually installed on the sides of the RV, are designed to “slide out” at the touch of a button, expanding the interior and increasing living area when the RV is parked and stationary. RV slide out construction plays a crucial role in ensuring the durability and safety of these expandable sections. Slide-outs are a game-changer in the world of recreational vehicles because they allow for more room without increasing the overall size of the RV when on the road.
When extended, slide-outs can contain various amenities such as sofas, dinettes, kitchens, or bedrooms, significantly enhancing the overall comfort and livability of the RV. This added space can make a significant difference, especially during longer trips or when traveling with a group of people. Understanding RV slide out construction helps RV owners maintain these features properly and appreciate the engineering behind their expanding living quarters.
RV slide-outs come in different types, including:
- Single Slide-Outs: Extend from one side of the RV, creating additional space in one area.
- Double or Dual Slide-Outs: Extend from both sides of the RV, providing extra space in two separate areas.
- Triple Slide-Outs: Extend from three sides of the RV, maximizing interior space for a more luxurious and spacious feel.
4 Basic Types of Slide-outs:
- Electric Rack and Pinion: The most common type of slide-out. It is used in lighter-weight RVs. There is an electric motor that turns the gear box which rotates a shaft and pushes or pulls the slide out.
- Hydraulic: This type is typically reserved for heavier, larger RVs. An electric motor-driven hydraulic pump is used to push or pull the slide out open or closed. One hydraulic system is often used for multiple slide-outs, and may also move the jacks.
- Tip-out: Often used to refer to slide-outs in general, but actually slide-outs are to be operated manually with hinges on the bottom to tip out with the help of pulling on a strap or by using an electric motor.
- Drawer: Lower RV storage compartments such as slide-out drawers. They are operated manually or by rack and pinion systems.
