I have a van with similar amount of cargo room as the Chrysler Pacifica. I had about 6 pieces of luggage and it fit with a few carry on luggage. At the same time you could feel the weight of the luggage. Some of my family did not pack light. lol I was driving to a cruise port that took an hour. If you are taking a long drive with a lot of luggage, I definitely would not over pack. I would probably condense the amount of luggage especially it's a long trip because it's not great driving with so much luggage.
