UNDERCOVER SC100D SwingCase storage
Product description
A clean, secure place for tools and gear is often the difference between a truck bed that feels organized and one that turns into a dumping ground. The RealTruck UnderCover SwingCase truck bed storage box helps you keep smaller items within reach while protecting them from everyday moisture. With a weather sealing approach and a lockable lid, it’s built for practical storage on the road, especially for drivers who want their setup to look as tidy as it works.
Designed to fit the driver side on compatible 2007 to 2019 Chevy and GMC Silverado and Sierra 2500 and 3500HD models, this storage box adds a dedicated compartment without forcing you to rearrange your whole truck. It’s also described as working with all tonneau covers, which makes it a smart add-on when you already have a cover plan in place. 😊

Key features
The UnderCover SwingCase is a truck bed storage box that focuses on quick access and everyday protection. You get a lid with a closure so the contents stay contained when you hit the road. RealTruck UnderCover storage is meant to complement existing tonneau setups, since it is described as functioning with all tonneau covers.



One of the biggest day-to-day advantages is moisture protection. The unit includes a humidity seal intended to help keep the contents dry, which is useful for hand tools, recovery items, and other gear that you do not want absorbing damp air. That protection matters most when your storage lives through changing weather, morning dew, and long stretches between cleaning.
You’ll also appreciate the straightforward installation approach. The product description highlights easy installation, so you are not stuck planning a major project before you can use it. And because the SwingCase is a driver side solution, it can make it easier to access your most-used items without reaching across the bed.

A practical note from the manufacturer description is that it is rated for up to 75 pounds of capacity. If you plan to load it heavily, keep that limit in mind so the box stays within the intended use. ✅

Pros

If you are trying to make your truck bed more functional, this storage box tackles the common pain points: scattered items and exposure to moisture. The humidity seal feature is intended to help keep contents dry, which can reduce the hassle of rust-prone tools and damp supplies. It also gives you a defined storage spot, so you can keep small gear from sliding around during everyday driving.
The lockable lid with closure helps add a layer of containment for items you want to keep secured. That is especially helpful when you are carrying work supplies, roadside essentials, or anything you want to avoid fumbling through when you need it fast. It is built around the idea that storage should be easy to live with, not just something you install and forget.



Another strength is fit and compatibility. The manufacturer description states that it fits compatible Silverado and Sierra 2500 and 3500HD models from 2007 to 2019, and that it works with all tonneau covers. That combination can simplify planning, whether you already own a tonneau or you are deciding one as part of your truck setup. 🔧
