Protecting Your Generator on the Road: Building a Generator Box


When it comes to traveling in an RV or fifth wheel, having a generator can be essential for powering various appliances and equipment. However, ensuring its safety and protection while on the road can be a challenge. In this article, we will explore the process of building a generator box to protect your generator during travel.

The Need for a Generator Box

As an avid traveler, you understand the importance of having a reliable generator to power your essential devices. However, carrying a generator without proper protection can lead to damage and potential risks. A generator box offers a practical solution by providing a secure and enclosed space for your generator, safeguarding it from external elements and potential theft.

The Challenges of Protecting the Generator

When considering the construction of a generator box, several challenges need to be addressed. One of the primary concerns is finding a suitable box size that can accommodate your generator's dimensions while allowing for necessary airflow. Additionally, ensuring stability and security are crucial factors to consider during the design process.

Choosing the Right Size Box

Selecting the right size box for your generator is essential to ensure a proper fit. While a larger box may seem ideal, it's important to take into account the available space on your RV or fifth wheel. A too snug fit may restrict airflow, while a box that is too large may compromise stability and make installation more challenging.

Modifying the Box to Fit the Generator

In some cases, you may encounter a situation where the available generator box is slightly smaller than your generator. While this may pose a challenge, various modification techniques can be employed to achieve a proper fit. By carefully assessing the available space and making necessary adjustments, such as removing the generator's feet, you can ensure a secure and snug fit within the box.

The Importance of Access and Accessibility

Easy access to the generator is crucial for maintenance and operation purposes. Incorporating a hatch or access panel in the generator box design allows for convenient reach while ensuring that the generator remains secure. Careful consideration should be given to the size and positioning of the hatch to accommodate the generator's dimensions effectively.

Ensuring Stability and Security

To prevent the generator from bouncing around during travel, it's vital to secure it within the generator box. Using eye bolts and a strap system, you can fasten the generator firmly, minimizing movement and potential damage. Reinforcing the generator box with sturdy materials, such as aluminum square tubing, adds strength and stability to the overall structure.

Addressing Water Intrusion Concerns

Protection against water intrusion is a critical aspect of designing an effective generator box. By sealing any gaps or openings with clear silicone and incorporating drainage holes in the box, you can minimize water damage and ensure proper ventilation. Routine inspections and maintenance are recommended to prevent debris from obstructing the drainage holes.

Maximizing Airflow for Optimal Performance

Maintaining adequate airflow is essential for optimal generator performance. To achieve this, consider installing protective grates or screens on the box openings. Choose materials that offer sufficient airflow while providing protection against debris and pests. Balancing airflow with protection is crucial to enhance the generator's efficiency and longevity.

Considering Pest Control Measures

When traveling, especially in rural areas, pests like wasps can pose a threat to the generator's functionality. Incorporating screen material in the intake areas can help prevent nesting and potential blockage without restricting necessary airflow. By periodically inspecting and cleaning the screen, you can ensure uninterrupted generator operation.

Future Plans for Extended Run Gas Tank

As an additional consideration, you may plan to incorporate an extended run gas tank setup in conjunction with the generator box. This allows for extended generator usage without constant refueling. Careful planning is required to ensure compatibility with your specific generator model and secure storage during travel.

Building a generator box for your RV or fifth wheel can provide the necessary protection and peace of mind while on the road. By addressing key factors such as size, stability, access, and airflow, you can create a secure space for your generator. With proper maintenance and periodic inspections, your generator box will serve its purpose effectively, ensuring reliable power wherever your travels take you.
