We provide a 3M single bulb seal that is placed around the perimeter on the bed rails and bulkhead to prevent water / dust from coming in. Our rear hatch also has a bulb seal that seats on the top of the tailgate in the closed position. In addition, we provide 2 pieces of butyl tape that can be placed at the bulkhead rail where there is a step down from the side plastic bed rail to the bulkhead to help prevent water / dust intrusion.
It is important to note that no truck bed is completely sealed, and some water intrusion may be possible although greatly reduced with the bulb seal. Likely water intrusion is often found around the tailgate perimeter.
The Expedition Cap Jeep Gladiator Application does not have a third brake light, due to the Gladiator already having a third brake light on the tailgate.
There will be an Overland Vehicle Systems cross bar option available. The cross bars will mount to the included cap rails (the rails that go parallel with the frame rails). The bars will have a dynamic weight rating of 325lbs and a static weight rating of 750lbs and have a rise of approximately 2” above the cap.
When using the optional Overland Vehicle Systems cross bars, the dynamic weight limit is 325lbs with a static weight limit is 750lbs.
The included rails were designed around the Overland Vehicle Systems optional cross bars. The included roof rails do have a 19mm slot which will allow for various systems. We will be testing various aftermarket crossbar systems and will eventually update the instructions on compatible systems.
The current design is a fixed rear window with no drop down / pass through accessibility.
Each Expedition Truck Cap will come with keyed-alike locks.
The Expedition Truck Cap cannot be locked or opened from the inside of the bed.
The Expedition Truck Cap vent is a fixed vent located above the glass on the panel located closest to the cab. The vent allows for air ventilation as well as circulation to reduce condensation inside the topper. It also allows air to escape during closing of all of the panels.
The only drilling involved in the Expedition is the hole you drill for the wiring portion of the Tacoma installation.
Where is the brake light on the Expedition Truck Cap for the Jeep Gladiator?
The brake lights have been removed from the Jeep Gladiator model due to the Jeep Gladiator already having a 3rd brake light.
As experienced Overlanders, we fully understand that things do not always go according to plan.
That is why we offer you our 30-Day Return Policy, so you can get back on the road for more adventures in a heartbeat.
