We ordered our 2007 Avalanche specifically to tow our Outback travel trailer. We equipped it with the optional 6.0L engine, 4.10 rear end, transmission oil cooler, heavy-duty 4L70E transmision and rear-view camera -- in other words, set up to tow. The Avalanche takes to the hills with confidence! 95% of the time, we use it as a comfortable family hauler. The redesigned interior matches our previous Sequoia in comfort and thoughtfulness of design. The drivetrain is not as smooth or refined as the Toyota's, but GM is getting closer. I can feel the 6.0L "burble" at idle, while the Toyota 4.7L was virtually silent. This is my first-ever GM vehicle -- and so far I have been pleased.
The versatility is unbeatable. The Avalanche is perfect for our family with two boys in sports and all the running around that entails. The cargo box serves as a secure and weather-tight trunk for groceries, sports gear, etc. Or, you can pull off the covers, load up the dogs or bikes and just go!
This vehicle has lots of other positives -- the XM radio, navigation system, and rear camera are wonderful features. However, GM needs to modernize its engine and transmission options. A 5-speed transmission will available in 2008 or 2009; but who else still uses a 4-speed transmission?
