5th-Wheel/Gooseneck Toolboxes & Tonneau Covers
Published on March 3, 2026

Do you need more than just a lid for your truck bed? The Stowe 2-in-1 tonneau cover and toolbox system was created just for you. We studied the concerns of experienced tonneau cover users—especially fifth-wheel and gooseneck trailer owners—and reinvented what a state-of-the-art cargo management system could be.
Where to Put Your Gear

With your truck bed occupied by a fifth-wheel or gooseneck system, the other contents of the box need to be relocated. Three alternate storage options to consider are:
- The truck’s back seat, which displaces occupant capacity
- The trailer, which occupies valuable storage or living space
- A storage compartment or toolbox, which has to be durable and weathertight, and meet tight packaging space requirements at the front of the truck bed
Choosing the Best Toolbox

Considering a toolbox? Several factors would make one the most compatible:
- Packaging clearancesTrailer nose to the face of the toolbox (the distance the toolbox extends into the bed)Trailer nose underside clearance during parking jackknife maneuvers—which needs a low-profile toolboxFifth-wheel hitch plate and handle to the face of the toolbox
- Trailer nose to the face of the toolbox (the distance the toolbox extends into the bed)
- Trailer nose underside clearance during parking jackknife maneuvers—which needs a low-profile toolbox
- Fifth-wheel hitch plate and handle to the face of the toolbox
- Usable capacity: If the toolbox is low-profile enough to allow for trailer nose swing, does it still have sufficient space to carry your gear?
- Tool-box access: With the trailer installed, can you still get into the storage box?
A Breakthrough Solution
Taking all these criteria into account, Stowe Cargo combined a spacious multifunction toolbox with an easy-to-attach hard tonneau cover. This unique 2-in-1 toolbox-and-tonneau system gives you generous weathertight capacity to secure your gear whether your trailer is coupled or not—without carrying your gear in your pickup’s back seat. Adding the truck-tough tonneau cover extends this protection to the entire bed.
It’s a breakthrough combination of better organization, easier access, and stronger protection from weather, theft, and motion damage. Plus, a premium appearance that’s actually worthy of your truck.
Most important, this innovative solution was created with fifth wheel and gooseneck trailer towing in mind.
