I love my 2003 Avalanche. It is the Northface Package with the cool grey leather and the grey metallic paint. My truck has everything and I bought a superchip and programed it. Also I put some nice tires on the stock rims, looks sweet. Also I chromed all the stock stuff out. For example, the back Chevy letters bought on ebay. MPG is pretty good in city, stays around 14, and highway about 19. The chip seems to help with my MPG.
