  While there are many small- and mid-sized SUVs on the road, they haven't driven the large sport-utility vehicles out of business. Some people buy full-size SUVs for their increased passenger space and extra cargo room, while others like the visibility that comes with a vehicle that sits higher off the ground than the cars around it. If you want one of the biggest 2011 SUVs available, you have three American-made models to choose from.
