An Eagle Cap Camper Snapped A Ram 3500 Dually In Half, Mopar Refuses $17,000 Repair Bill

2012 Ram 3500 for sale, on FB Marktplace, near me with 434,000 miles. Has a broken frame as shown in Picture below. Looks like a clean break. Maybe a weak spot in the frame right at the hole? Plus a diesel pulling hard in low gear with say a 4.10 axle puts a huge up twist on the frame at the front spring hanger.....
