I have to say my Tahoe LT (fully loaded) has been a great, great, vehicle. Drivetrain and 5.7 Vortec engine delivers. Plenty of room for people and my Siberian Husky in the back too (who loves the rear A/C) Aggressive BF Goodrich All Terrain T/As (functionally large but not monster truck silly) make Tahoe the big dog in the yard. A balanced truck with Bilstein gas charged shocks that rides like a dream on or off the road. Love the 4WD, towing capabilities, and the heated leather seats. I may not get the best gas mileage at $4.35/gal for Premium, but the power is there when I need it, and will safely win the physics game in the unfortunate event there is a collision.
Outstanding visibility, massive size, large comfy interior, power and road accelleration to spare. Drivetrain is robust and reliable. Easy to maintain, and easy access to engine. In winter storms, This big dog leads the sled team while the other SUV's sit on the sidleine (or spinning their wheels)
GM needs to improve the plastic intake manifold design so that it is not prone to gasket leakage (leads to coolant issues). Luckily, it was under warranty.
