DU-HA Storage Systems / Gun Cases - Whether you're a contractor, sportsman or simply someone looking for a great way to organize your pickup truck and keep your guns and gear safely out of sight, the DU-HA is perfect for you. The DU-HA allows you to store your gear, guns, tools, tow ropes, jumper cables, and so much more safely and securely underneath the back seat of your truck. FITMENT NOTES: Fits "Classic" Body Style only. Does NOT fit the "New Body" Style. Does NOT fit the Dodge Mega Cab. Does NOT fit with the factory navigation system.
