When buying any vehicle, you’ll want to know how many things will fit inside. Especially for SUV buyers, cargo space is essential. Who wants to buy a roomy full-size SUV that doesn’t have enough interior space for the cargo it’s carrying? That’s why the experts measured up to the latest model to find out which ones offer more storage space than others. If you’re looking for a full-size SUV with the most room behind the rear seat for cargo space, here are the top three options: the 2022 Jeep Wagoneer, Jeep Grand Wagoneer, and 2021 Chevrolet Suburban.
3. 2022 Jeep Wagoneer Series III
The 2022 Jeep Wagoneer Series III model offers the third largest cargo space in a full-size SUV. According to cars.com, the luxurious Jeep has 36.6 cubic feet behind the second row of seats and 16.4 cubic feet behind the third row. The first measurement is for when the third row is folded down and out of the way. The second number is for when you’re stowing something in the trunk behind a third row of passenger seats.
Unfortunately, the Series III version is the one that offers the most storage space. According to edmunds, buyers have to pay more than any other version for this model. It starts at $75,995, about $15,000 more than the base Series I model. Fortunately, the Series III model is exceptionally well equipped. It has luxurious features like heated second-row seats, power-reclining third-row seats, adaptive air suspension, and an on-demand two-speed transfer case.
2. 2022 Jeep Grand Wagoneer Series III

Next, the second-largest cargo space offered in a full-size SUV is in the 2022 Jeep Grand Wagoneer Series III. It’s just like the regular Wagoneer but even bigger for almost every dimension. It measures 38.9 cubic feet behind the second row of seats and 17.2 cubic feet behind the third row. Buyers of the Grand Wagoneer over the Wagoneer get a couple extra cubic feet for storing items in their full-size SUVs.
As with the standard Wagoneer, the Series III model is required. Again, it’s the top-of-the-line model that costs a whopping $109,995. However, the stretched Wagoneer is never affordable. Even the cheapest version of the Series I starts at $89,995, making the Grand Wagoneer a model for those with an unlimited budget. The upgraded trim adds features like ventilated second-row seats, a 23-speaker McIntosh audio system, and an infrared night vision camera with pedestrian and animal detection.
1. 2021 Chevrolet Suburban High Country

Finally, the full-size SUV with the most cargo space is the 2021 Chevrolet Suburban High Country. It has 41.8 cubic feet of space behind the second row and 23 cubic feet behind the third. That’s quite a bit more than the second-place model, beating it by nearly nine combined cubic feet. However, the High Country version is also the top-of-the-line Suburban model. Buyers looking for maximum cargo space will have to buy the more expensive version of the Chevy SUV.
According to Edmunds, the Suburban High Country starts at $73,595. That’s just over $20,000 more than the base model. However, it does get a unique 420-horsepower, 6.2-liter V8 engine, a rear pedestrian alert system, and a special grille with bronze accents. With Autotrader, 2021 Chevrolet Suburban High Country models are typically priced from $70,000 to $75,000. Prices vary by location, mileage, state and more.
The largest cargo space in large SUVs
In conclusion, cargo space is one of the most essential parts when buying a large SUV. Although extra seats are nice, sacrificing storage bins is never a good thing. Fortunately, with these three models, you’ll have plenty of room for passengers and cargo alike. The 2022 Jeep Wagoneer Series III, 2022 Jeep Grand Wagoneer Series III and 2021 Chevrolet Suburban High Country provide more cargo space than any other full-size SUV measured by Cars.com.
