2014: “December 26, 2013, my wife and I stopped at a rest stop in van horn, texas for a few hours rest. Our rv was not manufactured with a furnace air return duct. We had just bought a new dodge 3500 with a cummins diesel engine having all the bells & whistles (first for us). Waking up I decide to show off the (new to us) engine remote start feature. Before the engine started I was putting on my shoes to walk our pet. While waiting on our dog to relieve herself I heard my wife yelling out, exhaust is coming inside. …”
