Manufacturer floorplan images © their respective manufacturers. Specs checked October 19, 2026; exact-unit labels and production options may differ. “Not verified” or a dash means we have no confirmed value. “Not listed” means the applicable manufacturer equipment was checked but does not mention the feature; it does not mean “No.” “Conflicting data” means manufacturer entries disagree. “Optional” equipment is available but is not confirmed as standard. Camera prep does not confirm an installed camera. Weights are kept separate: unloaded weight, GVWR, cargo capacity, and hitch weight. Confirm every specification for the exact model year and configuration with the manufacturer. This tool does not establish towing compatibility.
