I'm nervous about cargo space, with 3 kids and being spoiled by the van for 6 years...
Looks like Traverse and Atlas have the most, followed by the Durango. Acadia, Volvo, and QX60 are a good bit smaller.
If you plan on ever using it for
especially towing something like a power boat or a camper, make sure it can handle the weight, both suspension and engine. Make absolutely certain it has the factory tow package installed. The Durango will have a "Towing" feature that helps prevent trailer sway. Ford has a similar feature, so I suppose most manufacturers offer something. Look at the maximum weight of boats or campers you would possibly buy for your family. That weight should be no more than about 80% of the maximum towing capacity of whatever vehicle you buy. Remember, you'll also have your whole family and maybe vacation
gear added weight. Learn about the difference between standard SUV tires, truck tires, and heavy duty tires for heavier towing.
There's a reason Chevy makes an extended Suburban, Ford makes the extended Expedition, Dodge makes the Durango V8 Hemi, etc.
A family of 5 with lots of gear and towing along a camper, a boat, a couple of jet skis, or a trailer with a couple or three four wheelers is FUN! Been there, done that from Bar Harbor, Maine along the Eastern Seaboard to Key West, Fla. and all the Gulf Coast. From Rodanthe, NC on the Outer Banks to Park City, Utah. Tombstone, Pikes Peak, Tetons, and all points in between. We wore out a Navigator, and I always wished we'd gotten a 10 cyl. Ford Excursion for the extra power over long mountain grades and more space. Always more space. And there is no mini van that can tow real weight.
