If you’re considering getting an enclosed trailer, whether for hauling cars, transporting goods, or turning it into a mobile workspace, you may wonder how to build one, how to add an A/C unit for enclosed trailer, and how much they weigh. In this article, we will answer all these questions and more.

How to Build an Enclosed Trailer

Building an enclosed trailer from scratch requires planning, time, and the right materials. Here’s a general guide to building your own:

  1. Frame Construction: The first step is to create the frame of the trailer. You’ll need steel or aluminum beams to build the frame that will support the structure. Make sure to weld the joints securely for a sturdy foundation.

  2. Flooring: Next, install a strong and durable floor. Most enclosed trailers use plywood or treated wood for the flooring, but you can also use aluminum for a lighter, rust-resistant option. Ensure the floor is level and securely attached to the frame.

  3. Wall Construction: For the walls, you can use sheet metal, wood paneling, or fiberglass, depending on the purpose of the trailer. The walls need to be strong enough to withstand hauling and weather conditions, so ensure the material is durable.

  4. Roof: The roof is another critical component. You can use metal, fiberglass, or even rubber for the roof material. Make sure to seal all seams to prevent leaks.

  5. Doors and Windows: Depending on the type of enclosed trailer you are building, you’ll need to install a rear door (or ramp) and possibly side doors or windows. Make sure the door mechanisms are durable and easy to operate.

  6. Wiring and Lighting: Once the basic structure is in place, you’ll need to install electrical wiring for lights, brake lights, and possibly air conditioning or other electrical needs.

A/C Unit for Enclosed Trailer

Adding an A/C unit to your enclosed trailer can make it more comfortable if you plan to use it as a mobile office, workshop, or living space. Here’s how to do it:

  1. Choose the Right Unit: Look for an A/C unit that fits the size of your trailer. A typical 5,000 to 10,000 BTU window A/C unit can work well for smaller trailers. For larger trailers, you may need a larger unit or a roof-mounted air conditioning system.

  2. Install Ventilation: Ensure proper ventilation in the trailer so the A/C unit can function efficiently. Ventilation also helps prevent moisture buildup inside the trailer.

  3. Mounting the Unit: If you’re using a window-style A/C, create an appropriate opening in the wall for the unit. For a roof-mounted unit, follow the manufacturer’s instructions to mount it securely on the roof of the trailer.

  4. Electrical Setup: Make sure your trailer’s electrical system can support the power needs of the A/C unit. You may need to upgrade your wiring or add a generator to run the system.

How Much Does an Enclosed Trailer Weigh?

The weight of an enclosed trailer depends on its size, construction materials, and whether it’s customized with features like an A/C unit or additional cargo space. Here’s a general overview of the weight:

  • Small Enclosed Trailers (6×12 or smaller): These trailers typically weigh between 1,000 lbs and 2,500 lbs, depending on the material and features.

  • Medium Enclosed Trailers (7×14 to 8×16): Expect these trailers to weigh between 2,500 lbs and 4,000 lbs.

  • Large Enclosed Trailers (8×20 and larger): These can weigh anywhere from 4,000 lbs to 7,000 lbs, or even more, depending on the build.

The weight of an enclosed trailer increases with its size, the materials used, and additional features like doors, windows, and insulation.

Conclusion

Building an enclosed trailer, adding an A/C unit, and understanding the trailer’s weight are important steps in ensuring your trailer serves your needs. Whether you’re constructing a trailer from scratch or purchasing a pre-built enclosed trailer, the right construction materials, features, and weight management are key to creating a functional and efficient mobile solution.
