Planning some road trips; might need a little extra storage for sleeping bags, camp chairs, luggage, and other bulky items. I already own a 1 1/4" cargo carrier and all-weather bag from my other vehicle. I will most likely just get a hitch installed and call it a day (4cyl). But first, Are there any advantages to a rooftop carrier? Curious why one would choose the rooftop method over the tow hitch/cargo carrier type setup. Seems like this way is easier to access, helps reduce drag (less MPG impact?), more flexible, and has more options for storage. Only thing holding me back is the fact that this vehicle has roof rails already which my last vehicle did not have. Thoughts?? Anyone have a great case to make for rooftop carriers? TIA..
