Shawn,

I've had my Tahoe hybrid since February, over 6000 miles. My mpg is at http://www.greenhybrid.com/compare/m.../car/6478.html

I was averaging right at 20.0, but took a slight hit last week driving from Dallas to Arkansas at70 mph with a bike rack on the back. I'm not sure if there are any other Tahoe's recording mileage, but look through cars listed as 'other'.
