Removing My RV Generator: A DIY Project to Save Space and Improve Efficiency

Are you tired of lugging around a heavy and bulky generator in your RV that you rarely use? Are you looking for ways to maximize storage space and improve the overall RVing experience? In this article, I will share with you a DIY project that I recently undertook - removing my generator and replacing it with a storage cabinet. Join me as I walk you through the step-by-step process and explore the benefits of this project.

Why I Decided to Get Rid of My Generator

Before we dive into the details of this project, you might be wondering why I would even consider getting rid of a generator. Well, the truth is, I haven't used it in years! With the advancements in solar power and off-grid equipment, my RV is now equipped to handle all my power needs without the need for a generator. Not only was the generator taking up valuable space in my RV, but it also added unnecessary weight. So, it made perfect sense for me to remove it and utilize that space for something more practical.

The Benefits of Removing a Generator

Removing a generator from your RV comes with numerous benefits. First and foremost, it frees up valuable storage space. In an RV, every square inch counts, and by removing the generator, you can utilize that space for extra storage. Whether it's for camping gear, tools, or any other items, having more storage options can greatly enhance your RVing experience.

Secondly, removing the generator reduces the overall weight of your RV. Generators can be quite heavy, weighing up to 300 pounds or more. By eliminating this weight, your RV becomes more fuel-efficient, making your travels lighter on the wallet and the environment.

Lastly, removing the generator simplifies your RV's electrical system. With one less piece of equipment to maintain and manage, you can enjoy a cleaner and more streamlined electrical setup, making troubleshooting and maintenance easier.

Step-by-Step Guide to Removing a Generator

Now, let's get into the nitty-gritty of the project. Before starting the removal process, it is essential to disconnect various connections, such as the fuel line, DC 12-volt connection, and AC connection. This ensures a safe and seamless removal. Once all the connections are disconnected and tidied up, it's time to tackle the task of actually removing the generator.

To safely remove the generator, you'll need to undo all the bolts securing it in place. A car jack can be handy in supporting the generator while removing the bolts. Once all the bolts are removed, carefully lower the generator and remove it from the RV. It's crucial to take your time and ensure a smooth removal process to avoid any damage to your RV or yourself.

Replacing the Generator with a Storage Cabinet

With the generator successfully removed, it's time to replace it with a storage cabinet. Choosing the right storage cabinet is crucial to maximize the space and functionality of your RV. Consider factors such as size, design, and material. Opt for a cabinet that complements the interior of your RV and offers ample storage space.

Installing the storage cabinet is relatively straightforward. Since the generator was previously mounted in a solid and anchored frame, the new cabinet can be built right into that existing frame. This makes the structure of the cabinet sturdy and secure. Additionally, adding galvanized sheet metal to the bottom of the cabinet further enhances its durability and protection against the elements.

Wiring and Electrical Considerations

During the installation process, it's essential to address any wiring and electrical considerations. Depending on your specific needs, you may want to allocate one side of the cabinet for electrical equipment and the other side for general storage. Carefully wire your electrical components into the cabinet, ensuring proper connections and safety precautions are taken. If you're uncertain about electrical work, it's advisable to consult a professional to avoid any mishaps.

Maximizing Storage Space in the RV

Now that you have a brand-new storage cabinet, it's time to make the most of the extra space. Organize your belongings efficiently, using bins, shelves, and dividers. Maximize every nook and cranny to ensure optimal storage capacity. Consider investing in space-saving solutions such as collapsible storage containers and vacuum sealing bags. With a well-organized storage cabinet, you'll be amazed at how much more you can pack for your RV adventures.

Other Uses for the Space Previously Occupied by the Generator

Apart from storage, the space previously occupied by the generator can be repurposed for various purposes. Some RV enthusiasts have transformed this area into a pet den, a mini-office, or even a wine cellar. The possibilities are endless. Get creative and tailor the space to your unique needs and interests.


Removing my generator and replacing it with a storage cabinet was one of the best decisions I made for my RV. It not only freed up space and reduced weight but also simplified my RV's electrical system. As an RV owner, it's important to reassess your equipment and make changes that enhance your RVing experience. So, if you find yourself with a generator you rarely use, consider taking on this DIY project. With a little time and effort, you can transform your RV's functionality and make every trip more enjoyable.
