This is my second avalanche going from a 2002 to a 2009. More bells and whistles but the performance is better in the 02.Some short changes on the 09 are sun visors 02 had 2 on each side,09 has one per side. No extenders on the 09,two on 02. Only one light in bed area, 02 had one on each side. 09 is air tight when doors are closed radio and nav are excellent. 02 still in family only different driver. Now has 90,000 miles on 02 and never been back to the dealer. Hope the 09 proves this good.
XM radio,on star, navigation and rear camera are excellent.
Go back to the double sun visors, extenders, storage are in rear seat in place of cup holders in pull down compartment.
