For brief stops while traveling I use the Hitch Bar Lock which I thought was included with the 1.25" Quick Rack now, along with a couple Wheel Locks as referenced in #2. The ability to fold the rack makes it easy to stash inside a trunk or back of an SUV for the overnight stops where you'll be taking the bike inside.
