Not possible....frame not designed to support the weight on that end. Changes the dynamics of the weight issue.
Not true, anything possible with metal. But like also said, will void warranty of frame. I put one on my 2014 model, with that being said. If I couldn't use my toys for what I want, then why have them. IMO
Herk: are those pictures resulting from stress to a frame from modifications or is it from regular use. I would think that anyone modifying the frame to add a trailer hitch may beef it up to exceed the manufacturers specs. Just saying.
Regardless of how well the hitch is welded to the stock frame, the entire frame from front to rear is not designed for the extra load and stress put on it by adding a hitch. You can do as you please as it belongs to you, but you are just asking for problems.
