These weights are all depending on various options that You can change on the trucks as well. As the truck's payload and towing capacity increases they also get heavier. This is because the frame gets stronger on them to be able to support the extra weight needed for towing. These weights are all pretty close to standard comparing them to other full size trucks that are on the market. GMC has started making more components on their trucks out of aluminum and this has helped the weight decrease in recent years.
