I have a 2001 dodge dakota. when new, i installed a curt manufacturing tow hitch. i take great care of my vehicles. i tow only on rare occasions, probably 6-10 days a year. recently, i noticed extreme corrosion on the side supports and main tube of the tow hitch. i have no other corrosion of this sort on my vehicle. the sides seem to be corroding in sheets (steel) as if it was a plywood. it is totally unsafe to tow anything while it is in this condition. it needs to be replaced. curt has a lifetime warrantee. i contacted them and sent pictures. i believe it may be inferior steel or coating from factory. anyways, they denied my claim. i wanted a replacement. i have original receipt and instructions. i am concerned that others my have this, and if not addressed could lead to a catastrophic towing accident as everything towed connects only to this accessory. *tr
