We have a Chevy Tahoe ('03). It's a v6, so gets OK gas mileage. We have 3 rows of seating, but the 3rd row can split in 1/2 (half of the row can be removed, so if you only want 1 person in the way back while the luggage is in the other part). We take up 2 kids and a huge dog crate along w/ luggage, etc. and it fits everything fine. I refuse to drive a carivan, so this is a great alternative.
