GMC has three main classes of trucks for sale as new vehicles on our lot in Orchard Park. There’s the GMC Canyon, perfect for off-roading or heading to the lake and taking care of light-duty tasks in Buffalo. There’s the GMC Sierra 1500, a light-duty workhorse for your job site work in Blasdell. Then, the GMC Sierra HD models give you the top towing and payload figures for worksites in West Seneca. 

Because these trucks have different capabilities, they also have different GMC truck bed sizes. Do you know which one works best for you? Find out more details about the GMC truck bed sizes with our guide from Robert Basil Buick GMC. We’re happy to help in any way we can!
