I have a 2001. 5 2500 RAM with the camper and tow packages. I tow an 8500 lb Wanderer RV trailer. The truck has only towed this trailer about 5 times to date. When I unhooked last weekend , I noticed the hole for the hitch pin on the trucks left side looked oval. Upon closer examination, It was! The pin wobbles around and the passenger side looks OK. I thought these hitches had to be tough. I know your not suppose to weld or drill into them because of their hardness. Has anyone heard of this before. I use a Draw-Tite weight distributing hitch. Thanks on any feed back.
