CT6 Trailer Hitch
 

I need to install a light duty trailer hitch on my 2017 CT6. But two things are stopping me. The first is the warning in the Owner's Manual that the selected hitch must be compatible with an aluminum frame. All the hitches I can find are made from steel and I am afraid of galvanic corrosion.

The second is the rather daunting installation process. One confirmed DIYer said it took him 8 hours to do it.

Does anyone have any recommendations for either concern? Or an installer near Buffalo NY?
