Do you think we can fit in an equinox (ie "midsize suv")? we will have 2 adults, 2 kids in carseats, a double stroller, and a couple of suitcases (plus some light groceries we will pick up on the way). The biggest issue is to/from the airport b/c that is when trunk space will be a premium. We haven't seen one IRL so we are having trouble gauging if we can fit. I am not worried about the passenger area. Can anyone provide some guidance? JJ
