Can honestly say this is most comfortable truck I have ever driven. I have only ever owned Dodge and cross shopped this with the new crew-cab Ram. The Avalanche drives as well as the Ram even with its new coil rear suspension. The Avalanche interior is very sophisticated - more SUV than truck.
Best seats I have ever sat in. Auto 4wd is excellent in winter weather we have had. Very impressed with highway mileage - pushing 20-21 if I drive 60- 65mph. Weathertight bed has been great.
Cabin air filtration would help with dust. Telescope steering could improve driving position somewhat. Would like a console organizer as standard rather than buying as an accessory.
