Hi there. Dirtdogs asked me to jump in with info on options for carrying stuff. We agree that putting a bunch of stuff on top of the car can get cumbersome, especially if you're going to need a ladder to get it down from there. I purchased from etrailer.com . They have custom hitches made for your car that just bolt into place. About $200, more or less. The same kind you can get from u-haul if you go there. Then get a hitch cargo carrier ($varies) and a hitch cargo carrier bag ( the Rola is $70). There are adapters to go from 1.25 inch to 2 inches and vice versa.(Our Subies hitch receiver is 2 in, and the carrier is 1.25in) Customer service from etrailer was pretty good when they had to replace my hitch for the Toyota that didn't fit right, they contacted the manufacturer to make one up for me from scratch.
The bag zips up to keep out water, and we've used it in snow conditions many times. With very little practice the whole thing can be placed and removed quickly. The carriers are made of iron, so pretty heavy. Watch those toes. Hope that helps
