In this fascinating video by How It’s Made, you’ll get an inside look at the process of building recreational vehicles (RVs). RVs are like your very own personal motel on wheels, providing the ultimate travel experience. Whether motorized or towable, RVs come in a range of options, from folding tent trailers to fully equipped travel trailers with bathrooms and kitchens. The video takes you through each step of the RV manufacturing process, from cutting steel bars to build the frame, to installing the plumbing fixtures and electrical wiring, all the way to the finishing touches like upholstery and decorative elements. By the end, you’ll have a newfound appreciation for the incredible craftsmanship that goes into creating these comfortable and versatile travel trailers.
Frame Construction
When constructing a recreational vehicle (RV), the first step is to build the frame. This involves cutting steel bars to the desired lengths using a saw. It is important to keep the saw cool by drenching it in coolant to lower heat caused by the intense friction. Once the steel bars are cut, holes are drilled for the bolts and screws that will be used to attach certain components later on. The frame parts are then soldered together to create a sturdy structure. To ensure safety, electrical wires are run through the frame, and rubber grommets are placed in the holes to prevent the wires from rubbing against the sharp metal edges.
Installing Tanks and Gas Lines
After the frame is constructed, the next step is to install the tanks and gas lines. Metal brackets are installed underneath the RV to hold the water and septic tanks securely in place. The tanks, made of heavy-duty polyethylene, are then attached to the frame. The white tank is for drinking water, while the first black tank is for the shower and sinks, and the second black tank is for the toilet. Once the tanks are installed, the gas lines for the stove, fridge, and heating system are put in place. All these appliances run on propane for easy and convenient use.
Building the Floor
Creating a solid and comfortable floor is an essential part of RV construction. To begin, a waterproof membrane is applied to protect the floor from any moisture. A spruce frame is then constructed and insulated with fiberglass wool for added warmth and soundproofing. Next, 5/8 plywood is installed as the flooring material. Vent holes are carefully cut to accommodate the forced air heating system, ensuring proper airflow throughout the RV.
Interior Construction
Once the floor is complete, attention turns to the interior construction of the RV. Cabinetry and furniture are installed, providing storage space and functional areas for daily living. Plumbing fixtures, connected to the water lines coming from the tanks beneath the floor, are carefully attached to ensure proper functionality. The interior walls are covered with vinyl paneling, as drywall would be too heavy for an RV. This paneling is mounted on a pine structure insulated with fiberglass wool, providing both insulation and a visually appealing interior. Throughout the interior, fiberglass wool is used for additional insulation, keeping the RV comfortable in various weather conditions.
Exterior Construction
Moving on to the exterior construction, the RV is covered with aluminum siding, providing durability and protection from the elements. At this stage, the electrical wiring for lights and appliances is completed, ensuring everything is in working order. The roof is then installed, using a pine structure with fiberglass wool insulation. The roofing material, called luan, is reinforced to withstand the extra weight of any cargo that may be placed on the roof. Various ventilation holes are cut out to allow for proper airflow inside the RV. To prevent any water penetration, a layer of high-performance waterproof rubber membrane is applied. With the membrane in place, vents are installed for the toilet, refrigerator, and air circulation. All joints and areas around the vents are caulked to create a watertight seal, protecting the RV from any potential leaks.
Final Installations
As the construction process nears completion, the final installations are carried out. Windows, doors, and awnings are carefully installed to provide functionality and enhance the aesthetics of the RV. Workers thoroughly check the water, gas, and electrical systems to ensure everything is working properly. In a seal test, a specialized machine applies air pressure from the inside out. If any water bubbles appear, it indicates a leak that needs to be repaired. Finally, upholstery and other decorative elements are added to create a comfortable and visually appealing interior, transforming the RV into a cozy home on wheels.
With careful attention to each step of the construction process, the end result is a high-quality recreational vehicle that is ready to hit the road. Whether it’s for a weekend getaway or a long-distance adventure, an RV provides a convenient and comfortable way to travel and experience the joys of the open road.
