The Lincoln Navigator gives you 34.3 cubic feet of cargo space behind the third row, while a Cadillac Escalade only has 25.5 cubic feet of room. Although, this number is fairly similar when you fold down all the seats. Most can agree that trunk volume is the priority. Chances are, your seats will be full more often than not, meaning your trunk will be the only place you have left to store your items when you need to pack for your next adventure.
