I am either going to sell my 100 series (or trade) or put time and money into the restoration of the rear area where the rust is bad enough the frame cannot support the install of a daggum trailer hitch. The undercarriage has surface rust in general, but the rear area is where it is worst. It's a 2004 with 255K miles, a lot of which were racked up by the previous owner who drove it mostly in snowy West Virginia. I reside in SC. I guess if anyone has fabricated or welded something in a similar situation that would work, I'm all ears. I would like to keep this vehicle...Thanks in advance
