Fitment notes (from OVS)
- Made for the 2009-2027 Ram 2500/3500 with the 6.4 ft bed. Not offered for the 8 ft bed.
- Ram trucks with RamBox beds are NOT compatible.
- Factory spare-tire mounts (Ram/Chevy) or other accessories that interfere must be removed before installing.
- "No-drill" refers to the clamps on the bed rails. Some trucks need one small hole drilled to wire the 3rd brake light; see the OVS instructions.
- No truck bed is fully waterproof. The seals greatly reduce water and dust, but some water may still get in, most often around the tailgate.
- The cap cannot be opened or locked from inside the bed.

Which Ram 2500/3500 bed sizes does this truck cap fit?
It fits 2009-2027 Ram 2500 and 3500 trucks with the 6.4 ft bed. OVS does not make this cap for the 8 ft bed.
Will it fit my Ram 2500/3500 with RamBox?
No. OVS says Ram trucks with the RamBox bed storage system are not compatible with the Expedition cap. Factory spare-tire mounts or other accessories that interfere with the installation must also be removed first. Contact us with your trim if you are unsure.
What is the difference between the PRO and PRO+?
The PRO has solid steel wing doors with no side windows. The PRO+ has windowed wing doors (tempered glass with a sliding side window) and a built-in MOLLE panel; because of that panel, OVS's add-on door and side-frame MOLLE panels do not fit the PRO+. Everything else is shared: front and rear glass windows, construction, finish, latches, rear security cage, roof rails, seals and the 3rd brake light. On this truck the PRO+ is $500 more at regular price; with the PRO on sale right now, the PRO+ is currently $1,100 more.
Do I have to drill my Ram 2500/3500 to install it?
No drilling is needed to mount the cap; it clamps to the bed rails. The included 3rd brake light has to be wired, and OVS notes some trucks need one small hole drilled for that wire. Follow the OVS installation instructions for your truck.
How long does installation take?
OVS rates the install at 1-2 hours. The cap is a 5-piece modular design that assembles on the truck.
Does it work with a tonneau cover or bed rail accessories?
OVS does not list tonneau cover or bed rail accessory compatibility. The cap clamps directly to the bed rails, and OVS says any accessories that interfere with the installation must be removed first. If you are unsure about a specific accessory, contact us before ordering.
How does the truck cap ship?
It is a large freight item that ships direct from Overland Vehicle Systems. The current lead time is shown with each model option.
OVS does not publish a formal packing list. Based on OVS's product information, the cap comes with:
- Expedition truck cap (5-piece modular shell) for the Ram 2500/3500 6.4 ft bed
- No-drill bed rail clamps
- Integrated roof rails (19 mm T-slot)
- 3rd brake light
- 3M single-bulb seal for the bed rails and bulkhead
- Rear hatch bulb seal
- 2 pieces of butyl tape for the bulkhead step-down
- Rear window security cage
- Keyed-alike locking latches
Sold separately: crossbars, add-on MOLLE panels (these do not fit the PRO+, which has a built-in MOLLE panel) and LED lighting kits.
