My Buying Guides on Under Trailer Tool Box
When I first decided to invest in an under trailer tool box, I wanted something durable, spacious, and easy to access. After some trial and error, I’ve gathered a few key points that helped me pick the perfect one. If you’re in the market for an under trailer tool box, here’s what I recommend considering:
1. Determine the Right Size for Your Needs
I started by measuring the available space under my trailer. Under trailer tool boxes come in various sizes, so knowing the dimensions you have to work with is essential. I made sure to leave enough clearance so the box wouldn’t interfere with the wheels or suspension. Also, think about what tools and equipment you’ll store — I made a list of items to estimate the internal volume I needed.
2. Choose the Best Material for Durability
For me, durability was a top priority since the box would be exposed to the elements and rough road conditions. Aluminum and steel are popular choices. Aluminum is lightweight and resistant to rust, which is great if you live in a humid or coastal area like I do. Steel boxes are heavier but offer excellent strength. I went with aluminum to keep weight down and avoid corrosion.
3. Consider the Mounting Style and Installation
I looked into how the box would attach to my trailer. Some tool boxes come with universal mounting brackets, while others require drilling or custom mounts. I preferred a toolbox that was easy to install and remove if needed. Checking the compatibility with your trailer frame or crossmembers can save a lot of hassle during installation.
4. Look for Weatherproof Features
Since the tool box is under the trailer, it’s exposed to rain, mud, and dust. I made sure mine had a tight seal with rubber gaskets to keep water out and prevent rust inside. Some boxes have drainage holes and weather-resistant locks, which I found very useful to protect my tools.
5. Evaluate Security Options
I don’t want anyone stealing my tools, so I chose a toolbox with a sturdy lock system. Some models offer key locks, padlocks, or even combination locks. I picked one with a heavy-duty lock that’s also weatherproof to keep my belongings safe and dry.
6. Accessibility and Convenience
I considered how easily I could access my tools while on the road. Some under trailer tool boxes have side-opening doors, while others open from the top. I preferred side doors for quick access without having to crouch or crawl under the trailer. Also, I checked if the lid stays open on its own or has gas struts for smooth operation.
7. Budget and Warranty
Price is always a factor. I set a budget but didn’t want to compromise on quality. Investing a bit more upfront for a reliable box paid off in the long run. Also, I looked for brands that offer a warranty so I could be confident in my purchase.
8. Read Customer Reviews and Recommendations
Before finalizing my choice, I read customer reviews and watched video demonstrations. Real user feedback gave me insight into the pros and cons of different models that specs alone couldn’t provide.

By keeping these points in mind, I found an under trailer tool box that fits my trailer perfectly, protects my tools, and makes my work easier. I hope my buying guide helps you pick the right one for your needs!
