[quote=""DCIV""]Can you open the rear hatch? What do you do when you park overnight As those you can’t lock down can you? I also worry about the angle. Wrong angle with the avalanche and trailer hitch and I’m scraping the driveway.

I believe they make lockable ones, but you may have to unload that at nighttime. I don't know if you'd be able to open the hatch or not, but I would suspect you couldn't.
[quote=""Chris GTO TT""]I get those fears, but Aaron's point is loading roof boxes on a full size suv is a major pain without a ladder.[/quote]
This, also most roof racks won't come close to the 500lbs a hitch mount carrier can handle.
