I don't know. I'm sure the Suburban's payload is higher, but last time our family (2 adults, a 13 year old, a 12 year old, a 10 year old and a 3 years old in a car seat) drove from WA to IA we packed 2 full size suitcases, 3 carry-on size suitcases, a cooler and my old football dufflebag just behind the 3rd row. Then we also had a pack-n-play, umbrella stroller, box of snacks, a pillow and book bag of entertainment stuff for each kid, box of diapers and diaper bag in the aisle between the bucket seats all the way back to the 3rd row. Then we had even more stuff to bring home once all the grandparents had bought the kids stuff. None of the kids was squished, or were touching each other.
