Hi everyone, I've been thinking about replacing my 2005 Toyota Tundra longbed with a Suburban. I assumed that all Suburbans would allow me to load 4x8 sheet goods in my back. My wife and I went to a local dealer to check out a late-model 'burb. Imagine my disappointment when I found out that the second-row seats tumble forward but don't fold flat! What the heck... They didn't have any used 2000-2006 generation models on the lot. Do these years provide a flat cargo surface for sliding 4x8 sheet goods into the back? If so, I might be able to talk 'the boss' into going for a low-mileage '06 instead. Thanks everyone!
