2005 has brought a couple of exterior changes. Most people probably won't even notice that the running boards, or assist steps, have been redesigned for better aerodynamics and, says Chevrolet, better durability.

But we will miss the side-by-side cargo doors that are no longer available at the rear. GM says they didn't sell very well, but we found them useful when pulling trailers because they would usually clear the trailer tongue jack. They also made it easier to control a dog while opening them. Nonetheless, for 2005, all Suburbans come with the one-piece rear hatch with separately opening glass that most families prefer. The hatch is lightweight and can be opened with one hand. It comes with a window wiper/washer, and the one-piece window affords the driver a good view rearward.

A puddle lamp mounted below the LT's side mirrors shines down to light up the perimeter. It can be turned on using the keyless remote. That's a nice feature when approaching the Suburban in a dark parking garage, as it illuminates underneath the vehicle. It can also be used in the backwoods to spot mud puddles before you step in them or to find things that were dropped or placed around the vehicle. We found them useful one night when we dropped our keys while climbing out of the vehicle.

The Suburban is 22 inches longer than a Chevy Tahoe. In most respects, it is identical to the more luxurious GMC Yukon XL.
