GMC Terrain: Compact Efficiency
The GMC Terrain delivers ideal proportions for drivers who want a high seating position and versatile cargo access without navigating a large vehicle footprint.
- Cargo behind 2nd row: 29.6 cu. ft. (ample space for 4-5 large suitcases or double strollers).
- Max Cargo Volume: 63.3 cu. ft. with 60/40 split-folding rear seats stowed.
- Fold-Flat Front Passenger Seat: Enables loading flat gear up to 8 feet long directly through the tailgate into the cabin.
- Garage Clearance: 183.4 inches overall length easily fits shorter residential garages in Riverhead and Suffolk County.
GMC Acadia: Mid-Size Versatility
The redesigned GMC Acadia bridges the gap between compact agility and full-size capability. It offers three true passenger rows while maintaining a unibody driving profile.
- Cargo behind 3rd row: 23.0 cu. ft. (holds groceries, youth sports bags, or carry-on luggage without folding seats).
- Cargo behind 2nd row: 57.3 cu. ft. when folding the 3rd row flat.
- Max Cargo Volume: 97.5 cu. ft. with all rear seating folded.
- Smart Slide Second Row: Allows quick third-row passenger loading even when child safety seats are installed in row two.
GMC Yukon & Yukon XL: Full-Size Authority
Built on full-size truck architectures with independent rear suspensions, the Yukon and extended Yukon XL deliver maximum cabin width, low load-floor heights, and massive cargo capacities.

- GMC Yukon XL: 41.5 cu. ft. behind 3rd row | 89.6 cu. ft. behind 2nd row | 144.7 cu. ft. max cargo.
- The XL Advantage: The extra 15.2 inches of overall length in the Yukon XL adds nearly 16 cubic feet of dedicated luggage room *behind* the third row.
- Power-Folding Controls: Available push-button controls in the rear cargo area allow quick folding of second and third rows.
Real-World Storage Scenarios for Long Island Drivers
North Fork Beach Gear
Packing coolers, pop-up tents, chairs, and bodyboards for a day at Smith Point or Orient Point is easy in the Acadia (57.3 cu. ft.) or Yukon (72.6 cu. ft.) with 3rd-row seats folded.
4x8 Sheet Plywood
Thanks to the wide load floor between the wheel wells, the full-size GMC Yukon XL can carry standard 4' x 8' building materials flat on the load floor with rear seats folded.
Full Luggage + 7 Passengers
If you regularly carry 7 passengers AND full luggage for trips to JFK or MacAuthur Airport, the Yukon XL’s 41.5 cu. ft. rear trunk space eliminates the need for roof cargo boxes.
