Going on a 2000+ mile trip for the 4th of July(Heading up to Mount Rushmore and then back down through Colorado Springs) and since the dog crate and the ice chest will be in the very back, there won't be much room for the actual luggage and I was wondering which would work best, I already have a tow hitch, but would need to also buy the crossbars if I were to put anything up top. Any advice on taking a roadtrip in the Rogue with 4 adults and a dog?
A Tow Hitch mounted cargo carrier such as this curt one:

A rooftop cargo basket like this:

A rooftop cargo bag like this:

Or a rooftop cargo box like this:
