I don't know when the '07 is coming out. But I do know that the 2007 is going to be a much larger truck (wider) and rated for 10,000 pound towing capacity. My Tundra is a limited 4x4 and I usually put it in four wheel because I have it and it's a button. But next time I get gas, I'll try it in 2 wheel and I'll let you know. My boat probably weighs about 5800 pounds and I've never had a problem taking it out of the water.
