Don't buy a Tahoe/Yukon before driving a Nissan Armada. We had a 2004 that we drove from 65k to 120k and it was flawless. Really fantastic DOHC V8, bigger 2nd row by far than the domestics, good sized fold flat 3rd row, good space behind the 3rd row. Lots of thoughtful touches, like a one handle second row fold mechanism that was easy enough for my kids to do. We drove all of the competitors and the Armada was by far the favorite, if we were buying a new SUV we would get another.

The Sequoia is nice but pricey for what you get. The Expedition is seriously dated and underpowered, Ford has really let it languish without update. The Durango is nice but not real big inside. As mentioned before by others, the Tahoe/Yukon are pretty nice to drive and a big improvement on past cheap GM interiors. Used 100 or 200 series Land Cruiser would be a great truck. For an unconventional choice you should look for a used TDI Audi Q7. Massive towing power and I think about 26 MPG highway.

One other unconventional suggestion, our family car is a 2012 F150 SuperCrew 4x4. We got a loaded XLT brand new for about $33k. The 2nd row is massive, much bigger than any SUV. It has a front bench with folding console so it seats 6. We put in a Bedrug and fiberglass tonneau cover so we have a huge lockable trunk. With the 5.0 I think our tow rating is 9500, and the Ecoboost is more like 11,000. It's basically an SUV with a huge trunk and more towing ability.
