GM 2500/3500 Truck Cap FAQs
Will this fit my 2020-2026 GM 2500/3500 with the 8ft long bed?
No, this specific product listing is tailored exclusively for the 6.9-foot short bed. If you have the 8-foot long bed, you will need the matching long bed version of this cap.
How much weight can the OVS Expedition Truck Cap hold?
The Expedition Truck Cap features integrated roof rails that support up to 325 lbs of dynamic (moving) weight and 750 lbs of static (parked) weight when paired with optional crossbars. This makes it perfect for mounting heavy overlanding gear or a roof-top tent.
Is the Expedition Truck Cap waterproof?
Yes. It is engineered with waterproof perimeter seals, a 3M single bulb seal, and butyl tape to keep your cargo protected from rain, snow, and trail dust.
Does installing this cap require drilling into my GM 2500/3500?
The main structure uses a modular clamping system that attaches directly to the factory utility tracks in your GM 2500/3500 bed. However, GM 2500/3500 models do require one small drilled hole to route wiring for the third brake light.
Does a truck cap improve gas mileage?
Yes, adding a truck cap can reduce the aerodynamic drag created by an open truck bed and tailgate, potentially improving your truck's highway fuel efficiency.
Are the latches lockable?
Yes. Each heavy-duty latch includes keyed-alike locks to ensure your expensive gear and tools stay secure inside the truck cap.
