I had a Thule tray mount until I stumbled across a used hanger style for 20 bucks in a second hand store. I didn't need it, but looking at it I figured it would make a great work bench and it has. I don't have the Thule anymore because I'm always using the hanger anyway. It holds both of my bikes and with just one on it I can do all kinds of work on the bike. It also folds up for easy storage. When I'm on the road I use a locking pin on the receiver and a couple of locking cables to secure the bikes to the carrier. It's not perfect, but it's better than nothing.
