The 2018 GMC Sierra 1500 features a total cargo space of 11.3 cu.ft.. There's enough room available to carry the luggage of five for a weekend. For a better perspective, the cargo can accommodate at least two large suitcases and a few small backpacks as well. For additional storage space, you can further lower the rear seats to push in a couple of more big boxes inside the truck.
