the hitch doesn't look that bad at all, if you find an original one, (unicorn) or the an aftermarket one they look pretty much like any hitch would. the key is to get the wiring harness (ESCtuning has the kits) youll need the plug (7 pin connector --> 4 pin) the harness that connects to the wiring inside the rear passenger side plug, as well as the trailering module that plugs into the wiring that ends in the battery compartment, the module deactivates the rear PDC , and lets the truck know youre towing once something is connected to it!
its a pretty easy install, lots of tutorials on here etc.
ive hauled my jeep home on a car trailer without trailer brakes with no issues!
good luck!
