Really, any of the full size SUVs should be fine, as long as they are property equipped.
Expedition, Sequoia, Tahoe/Yukon, Suburban, Armada.
They all come with a wide array of options.
I know we love our Suburban. Would be hard to find a more comfortable vehicle, w/ 2nd row heated captain chairs, all the other amenities.
Although for towing, I would probably go with the Expedition ecoboost, if you're buying new.
Crew cab pickups can get pretty well equipped, too. The rear seat in my F150 has tons of leg room, and is very comfortable. With only 2 kids, you have a lot of options.
Good luck!
