Shawn,
Congrats on the Tahoe Hybrid. You are doing better than my (non-hybrid) minivan for gas mileage, and I'm certain your vehicle is much larger.
Sounds like GM will have their Tahoe represented at
Hybridfest this year, I'll be interested to hear people's feedback about it.
Glad you are keeping your sense of humor regarding Tahoe Hybrid discrimination for now. I look forward to hearing more about how things go for you. When did you get you're Tahoe and what part of the country are you in?
