My head is spinning from reading so many posts on the towing, so I don't even know, if I am coming or going!!!

I do have an OEM hitch, installed by previous owner, with the module in the battery compartment and hopefully all the correct struts under the bumper.

I need to get a UHaul trailer to haul some pieces of furniture for about 20 miles one way (and go empty 20 miles back), and before stepping into a UHaul place, I wanted to know what kind of hitch mount, or ball or whatever that thing is called that I need, and also, if I need any kind of electrical adapter to go from the OEM electrical outlet to the UHaul electrical inlet. I think I saw something the ECS guys were selling for an adapter, not sure if I need it or not, but I have not seen that ball thingy being offered as an OEM device.

An advice would be appreciated.

thank you,
