Hi,Tuffcookie!
We, like Piglet's Pal, decided to go with a soft car-top carrier, and have been very pleased with it. The brand name is AXIUS, and the box it came in is about the size of a large shoe box. The product is called a "Rack-Pack Roof Top Cargo Bag", and it has 15 cubic feet of usable space! We were able to pack 4 large pilot cases and 2 small(Disney) suitcases and 4 12-packs of coke(cans) in ours for our trip in June. Even though it rained hard on the way home, nothing got wet in it, even though the box states it is water-resistant as opposed to waterproof. There is a listing of vehicles on the back that are equipped with the proper luggage rack for this product, and the Camry is not listed, but the 4-Runner, landcruiser, and Sienna are. I am sure they make a smaller version for cars. I purchased ours at a K-mart that was closing back in April for $22(reg. price was @$50). We were looking for something that would not require a lot of storage space while not in use, and had to be easy to use(as I am so not technical)and this thing is perfect. We checked with our GMC dealer first, and the price for their carriers were more than we wanted to spend, however I used that info to search for a carrier that would fit our van(sizewise). Turns out my luggage rack would hold 2 of the AXIUS carriers, so I am kicking myself for not getting another one!
