I have the Stowaway, and we used it traveling for Christmas. It worked great for us! I did get the exhaust shield, but not sure it was needed. It did seem to sit higher than the exhaust pipes. I put it on, just to be sure. The hitch kind of angles up some, which moves it out of the way, I think. I can get a better picture of that in a bit. We had 4 carry ons, plus some gifts, wrapping paper, puzzle mat, bags of clothes for my niece & nephew...., 5 carry ons on the way back. It was super easy to swing it out and open the tailgate. We drove through snow, sleet & rain, and everything stayed dry. I did also get the locking hitch & the stabilizer.
Obviously, the backup camera is not usable (just had to look), and the sensors will go off. The only other thing was I noticed that occasionally, it must have just shifted enough to trigger the blind spot warning. It was very solid, but must just be right at the edge. It wasn't constantly, just randomly, so made sure to triple check when changing lanes.
