I have a question, does anyone know what is that max level of water the Avalanche can drive through without getting stuck. My neighborhood is flooded with about 1.5 feet of water at the highest areas. I need to get to places to help with flood control. is it possible for me to drive through it? And would I would use 4 Wheel Drive right? I'd rather have an idea now than experience it first hand. I have stock suspension with Z-71 package from 2002.
