Planning and design

Define the Purpose and Features:

Start by outlining the intended use of your camper. Will it be for occasional weekend trips or extended off-grid living? This will help determine the necessary features, such as sleeping capacity, kitchen facilities, and water storage. Consider your must-have amenities and any unique features you want to incorporate.

Choose the Right Base Vehicle:

Select a suitable vehicle to serve as the foundation for your camper. Consider the size, weight capacity, and towing capabilities of the vehicle. Ensure that the vehicle can handle the additional weight of the camper and any equipment you plan to bring.

Create Detailed Designs:

Develop detailed blueprints or drawings of your camper's design. Utilize tools like AutoCAD to create precise plans, saving time and reducing errors during construction. Consider the overall dimensions, layout, and placement of windows, doors, and other features. Mark the positions of screws, fixtures, and other fixings for easier assembly.

Select Appropriate Materials:

Choose materials that are lightweight yet durable and suitable for the climate and weather conditions you expect to encounter. For the frame, consider using materials such as extruded aluminum, lightweight wood like cedar, or steel. For the walls and roof, opt for waterproof and insulated materials, such as plywood with insulation and vapor protection.

Plan for Electrical and Plumbing:

If you intend to include electrical systems or plumbing, plan accordingly. Consider your power source, battery storage, and the number of electrical outlets you'll need. For plumbing, decide on water storage and waste management solutions, including freshwater tanks, greywater disposal, and toilet options.

Weight Distribution and Stability:

Ensure your design considers weight distribution and stability. A well-designed frame camper should have a low center of gravity and proper weight distribution to prevent tipping. Consider adding features like stabilizer jacks or additional support struts to enhance stability.

Remember to allow for flexibility in your design, as you may encounter unexpected challenges during construction. Take the time to research and plan thoroughly, drawing inspiration from existing camper designs and online resources.

Materials and tools

The materials and tools you will need to build a frame camper will depend on your specific design and requirements. Here is a list of materials and tools that can be used, depending on your preferences and skills:

Materials:

  • Wood: Plywood, construction lumber (e.g. pine), cedar, framing lumber
  • Metal: Aluminium, steel, iron
  • Insulation: Foam board, insulation foam, tar plastic, vapour barrier plastic
  • Roofing: Shingles, waterproof tarps
  • Windows and doors: Plastic or aluminium windows and doors, rubber window seals, acrylic paint for plywood edges
  • Electrical: LED lights, sockets, switches, circuit breakers, wire connectors, batteries
  • Miscellaneous: Hinges, screws, glue, weather stripping, waterproofing materials, paint

Tools:

  • Electrical screwdriver
  • Spirit level
  • Saw (jigsaw, circular saw)
  • Drill
  • Measuring tools: Tape measure, ruler
  • Protective gear: Work gloves, eye protection, respirator
  • Welding equipment (if working with metal)
  • Sandpaper and paintbrushes (if painting the frame)

When selecting your materials, consider the weight, durability, and water resistance of the frame camper. For example, cedar is lightweight and resistant to moisture, while aluminium is strong and durable but may be more expensive. Plywood is a versatile and affordable option for the frame and walls, but ensure it is an appropriate thickness for your needs.

Additionally, consider the tools you will need for assembly. Basic woodworking tools such as a drill, saw, and screwdriver may be sufficient, but if you plan to work with metal, you will need access to welding equipment and metalworking tools. Always prioritise your safety by wearing protective gear, including work gloves, eye protection, and a respirator when necessary.

Building the frame

Planning and Materials

Start by planning the dimensions and structure of your camper frame. Consider the size of your sleeping area and the overall length and width of the camper. You will need materials such as wood, metal, or aluminium for the frame, as well as tools like a jigsaw, circular saw, electrical screwdriver, and spirit level.

Foundation

Begin constructing the frame by creating a sturdy base. Form a wooden rectangle that fits the dimensions of your trailer bed and fix it securely in place. Ensure the foundation is level and stable, as it will bear the weight of the entire structure.

Walls

The next step is to build the walls of your camper frame. Raise the back wall first, followed by the left and right side walls. Ensure that each wall is sturdy and firmly attached to the foundation. Consider adding extra support, such as iron corners, for enhanced rigidity.

Roof Studs and Front Wall

After the walls are in place, it's time to focus on the upper section of the frame. Install the roof studs, which will provide support for the roof itself. Once the studs are in place, construct the front wall, ensuring it aligns with the slope of the roof.

Adjustments and Reinforcements

At this point, you may need to make adjustments to the frame to ensure it is not too bulky or heavy. Carefully evaluate the structure and remove any unnecessary wooden elements, being mindful of maintaining the overall integrity of the frame.

Final Touches

Once you're satisfied with the frame's structure, add the plywood panels to enclose the space. Ensure all corners and joints are securely fastened, creating a solid shell for your camper.

Building a camper frame is a challenging yet rewarding project. Take your time, plan carefully, and don't be afraid to make adjustments as you go. With dedication and attention to detail, you'll soon have a sturdy and reliable camper frame ready for your outdoor excursions.

Adding walls and a roof

Once your wooden frame is complete, you can add a layer of aluminium or ACM panels on the outside for protection and rigidity. ACM panels are strong and lightweight, but they can be heavy, so consider the weight of your overall build. You can also use plywood panels, which are more affordable and water-resistant. If you're looking for a more lightweight option, consider using high-density foam with a layer of plywood. This will reduce the overall weight of your camper, making it easier to tow.

For the roof, you can use a combination of wood and aluminium, similar to the walls. Ensure that the roof is sturdy enough to walk on and add gas struts to support the weight of the roof when it is popped up. Consider adding a waterproof layer, such as tar plastic or vinyl siding, to prevent leaks.

Finally, don't forget to include windows and a door in your design. You can purchase these from a local manufacturer or supplier. Mark the positions of these features on your frame before adding the walls and roof to ensure a proper fit.
