Yes, those Thule racks are ideal and many look quite aerodynamic. Like you said, I'd be looking at $700+.

The idea is to save money from flying all over the place, by going on camping road-trips for awhile.

Personally, I'd bungee a big duffel on the trunk-mounted roof rack. When I needed to get in the trunk, take the duffel off. I don't think it'd be that bad.

Thanks for the input and offer, though.
