The Curt hitch part # C13190 that you referenced is the correct hitch for your 2017 Mercedes GLS 450 and while it does not come with wiring the correct kit would be the part # 119250KIT which installs without requiring splicing wires. Install instructions link attached.
Towing with the hitch and wiring I mentioned would not interfere with the active curve system either which works to keep the vehicle level through corners and bumps. If your vehicle had this feature there would be a dial on the center console that would allow you to select a few different modes like comp, sport, etc.
If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag.
If the ball mount kit does not include a ball mount with the right rise or drop to tow the trailer level, check out the link I have included that explains how to measure to choose a ball mount to tow the trailer level.
