I noticed the passenger floorboard was very warm, almost hot, after driving 100 miles home after a few hours of off roading. The rig is a 94 with 150,000 miles. Obviously the heat is coming from the Catalytic Converter. My jacket, that was on the floorboard, felt like it just came out of the clothes dryer on the hot setting. Is this much heat common or am I just being paranoid?
