I actually had settled on an Expedition and was shopping around when I decided to try the Tahoe. What a difference! The ride and power were a huge step up from the Expedition. The interior seats are soft and comfy, and I love all of the gadgets. I tow a trailer regularly (2-3 times a week) and I was amazed at how well the "tow/haul" mode worked. I was thinking that it would just turn off overdrive, but actually it changes the shift points to allow the vehicle to act like it does when it's unloaded. Also, the autoride feature is the bomb- it levels out the vehicle suspension when it's under load. Gas mileage is much better than the Ford.
Autoride, Tow/Haul, automatic headlights, power seats. Lots of great features. Great power from the 5.3l v8!
