This compact profile suits owners who need durable storage without blocking bed access.

The RealTruck SwingCase Passenger Side is designed for 2015-2020 Ford F-150 models. It features a larger footprint, measuring 34 inches wide and 34 inches long. Both units weigh 16 pounds and come in black. You should select the model that matches your truck year and mounting preference.

Where UNDERCOVER Fits Your Needs

UNDERCOVER’s current range targets owners of specific Ford trucks who need durable, side-mounted storage. The lineup includes the SwingCase Driver Side for 1999-2016 F-250/350 models and the Passenger Side unit for 2015-2020 F-150s. Both units share a black finish and weigh 16 pounds. Dimensions vary by side, with widths and lengths swapping between 8.5 and 34 inches. You will not find lighting options or universal fitment in this selection. The brand focuses strictly on secure, wheel-well-adjacent storage for these specific bed layouts. If your truck model or mounting preference falls outside these specs, this range may not suit you.

How to choose the right one

1. Verify exact truck fitment

   You must match the tool box to your specific truck model and year. The data shows distinct units for different Ford trucks. The driver-side case fits 1999-2016 F-250/350 Super Duty models. The passenger-side unit is designed for 2015-2020 F-150s. Do not assume interchangeability between these models. Check the compatible truck field in the specifications. Choosing the wrong fitment will result in installation failure. Ensure your vehicle year falls within the stated range before purchasing.

2. Check side mounting position

   Decide whether you need driver-side or passenger-side storage. This choice depends on your bed layout and access preferences. The driver-side case, model SC200D, mounts near the wheel well on the left. The passenger-side case, model SC203P, mounts on the right. Select the side that best suits your daily loading habits. The position affects how you access the bed. Verify the size label in the specs. This ensures the unit clears your tonneau cover rails and other accessories.

3. Measure available bed space

   Compare the tool box dimensions against your truck bed. The driver-side unit measures 16 inches in length, 8.5 inches in width, and 34 inches in height. The passenger-side unit is larger, measuring 34 inches in length and width, with a height of 16 inches. These dimensions determine how much bed space remains. Ensure the unit fits without obstructing your tonneau cover. Measure your bed area carefully. The height spec is critical for clearance under rolling covers. Use these numbers to plan your cargo layout effectively.

4. Assess weight and durability

   Consider the weight of the unit for installation and daily use. Both listed models weigh 16 pounds. This weight suggests a sturdy construction suitable for heavy tools. A heavier unit may offer better vibration resistance. Check the weight spec to gauge build quality. Heavier cases often use thicker materials. This impacts long-term durability in rugged conditions. Ensure your mounting points can support the load. The 16-pound weight is manageable for most users. It provides a balance of strength and ease of handling.

5. Confirm color and finish

   Check the color specification to ensure it matches your truck. Both models listed are black. This is a common color that blends with most truck beds and tonneau covers. The black finish may help hide scratches and dirt. Verify the color in the product specs. A mismatched color can look out of place. The black option is versatile for various truck colors. Ensure the finish type meets your aesthetic preferences. The data confirms a consistent black appearance across the lineup. This simplifies the visual integration with your existing truck accessories.
