I'm completely illiterate when it comes to most things automotive and I need help. I'm wanting to get some type of cargo basket for the roof of my SUV (2013 Ford Escape) but I need some strong enough roof racks/rails/crossbar to support the basket/cargo weight I'll get and I'm not even sure what the difference is between a rail, rack etc. All I know is that the top of my car is bare with only the weather strips which appear to be made for removing (for things like this). What do I specifically need to buy? What brands make the best products for this type of thing? Any help would be much appreciated. This is all foreign territory to me and my local ford dealer was incredibly unhelpful.
