If the 3rd row matters, don't get a Tahoe or Yukon (SWB). The 3rd row is tight and there's almost no cargo space behind the 3rd row when it's in use. The second generation Expedition (with IRS) has a much more comfortable 3rd row, and more cargo space behind the 3rd row, than the Tahoe does in a SWB vehicle. If I wanted to avoid the OAL of a Suburban or Expedition EL and needed to use the third row while carrying anything, I'd get an Expedition. If you don't mind the wheelbase and OAL, I'd get a Suburban or Yukon XL due to aftermarket support. These LWB full-size SUVs are still shorter than an extended-cab 6.5' bed or crew-cab 5.5' bed half-ton truck, on par with a regular cab long bed truck. The Tahoe and Yukon are roughly the same wheelbase and length as a regular cab short bed truck. The Expedition splits the difference in size between the Tahoe and Suburban, but it lands closer to the Suburban than the Tahoe in OAL and wheelbase.
