Why Add A Room To The Trailer Is Necessary
When I decided to add a room to my trailer, it was because I needed more space to live comfortably. Trailers are great for mobility and simplicity, but they can feel cramped quickly, especially if you’re spending a lot of time inside. Adding a room gave me the extra square footage I needed to relax, work, and store my belongings without feeling cluttered.
Another reason I found it necessary was to create distinct living areas. Without separate rooms, everything blends together—sleeping, cooking, and lounging all happen in one spot. By adding a room, I was able to separate my sleeping area from my living space, which improved my daily routine and gave me a sense of privacy.
Lastly, expanding my trailer increased its overall value and functionality. Whether it’s for hosting friends or simply having a quiet corner to myself, that extra room made a huge difference. It wasn’t just about having more space; it was about making my trailer feel more like a true home.
My Buying Guides on Add A Room To The Trailer
Adding an extra room to your trailer can completely transform your travel experience, giving you more space and comfort on the road. When I decided to expand my trailer, I learned a lot about what to consider before making the investment. Here’s my comprehensive guide to help you make the best choice for your needs.
1. Assess Your Space and Needs
Before buying an add-a-room, I first measured the available exterior space and thought about how I planned to use the extra room. Were you looking for more sleeping space, a dining area, or storage? Knowing this helped me choose the right size and style.
2. Types of Add-A-Room Extensions
There are several options to consider:
- Pop-out Rooms: These extend from the side of the trailer, often with slide-outs or fold-outs. Great if you want a more permanent space.
- Screen Rooms: These provide a bug-free outdoor space with mesh walls and are perfect for relaxing outside without insects.
- Awning Rooms: Attached to your awning, these give extra shade and privacy but are usually less enclosed than other options.
I found that deciding on the type first narrowed down my choices significantly.
3. Material and Durability
Since I planned to use the add-a-room in different weather conditions, I looked for durable, waterproof materials with sturdy frames. Some rooms use heavy-duty polyester or vinyl, while others have aluminum frames for better support. Make sure the materials are easy to clean and resistant to mold or mildew.
4. Ease of Setup and Storage
One thing I paid close attention to was how easy the add-a-room was to set up and pack away. Some models take less than 10 minutes to assemble, which is ideal when you’re on the move. Also, consider where you will store the room when not in use—does it fold compactly, and does your trailer have enough storage space?
5. Compatibility with Your Trailer
Not all add-a-rooms fit every trailer model. I checked the dimensions and attachment methods to ensure compatibility. Some are designed for specific brands or trailer types, so double-checking this helped avoid any surprises.
6. Ventilation and Lighting
Good ventilation is key to comfort. I looked for add-a-rooms with mesh windows or vents that could be opened and closed easily. Some even have built-in lights or ports for electrical hookups, which can be a great bonus if you want to use the space at night.
7. Budget and Value
Prices vary widely depending on size, materials, and features. I set a budget upfront but also considered the long-term value. Spending a bit more for durability and ease of use paid off in the end because I use the add-a-room regularly.
8. Reviews and Recommendations
Finally, I read user reviews and asked fellow RVers about their experiences. Real-world feedback gave me insight into what worked well and what to avoid.
Adding a room to your trailer can enhance your camping experience by providing extra space and comfort. By considering your needs, trailer compatibility, materials, and ease of use, you can find the perfect add-a-room that fits your lifestyle. I hope my guide helps you make an informed decision!
