Engine Exhaust System problems of the 2013 Ford F-350

While towing our fifth-wheel trailer with our Ford f350 drw truck, the diesel particulate filter (dpf) caught fire. While towing our fifth-wheel, we turned from the highway onto a city street in mesa, az. We heard a loud "pop" and thought we blew a tire. After pulling over and checking that all tires were fine, we continued on. We noticed reduced power to the truck and the turbo boost was zero. We pulled over again to look for signs of a problem. We looked under the hood and did not see any obvious hoses blown or issues. The truck was still running, so we continued on slowly as we were almost home. Near ellsworth/thomas road in mesa, I got a notice, "reduced engine power," as my 14yo son yelled, "there's smoke coming out of the truck. " we pulled over again and my wife and son saw flames shooting out of the tailpipe and the exhaust system was glowing red hot. The dpf was blowing flams out towards the ground. We emptied a fire extinguisher with no effect. Our trailer has a water hose so we sprayed water on it for about 10 min to cool it down and stop it from reigniting. We did not call police as my wife and I share nearly 40 years of law enforcement experience. We extinguished the fire and called for a tow. After $10,000 in repairs, we have received no response from Ford. We have not filed an insurance claim yet and are working to contact Ford again. Ford knows there is a problem with the def/dpf systems. Drivers have no instrumentation to see the temp readings on the four temp gauges along the exhaust system. How are there no error codes or notices when a vehicle is on fire??? my and my wife's experience handling emergencies prevented a total loss of our vehicle and potential death of our family. Pics attached. Pics of red hot exhaust are not our vehicle, but a vehicle that had the same issue. This is what ours looked like.

1. Severe engine rattle and then severe shaking of entire truck due to exhaust regenerative system. Truck becomes hard to control on highway and presents danger in heavy traffic situations. First incident was taken in for repair; second incident occurred approximately seven months later and was told by dealer service representative that in order for the exhaust regenerative system to work properly we had to watch for the "cleaning exhaust system" message to appear (which only flashes on for approximately 5 seconds and requires eyes off the road) and then drive an additional 20 miles at speeds above 50 mph for the regeneration system to complete. Unacceptable when living in an area where speed limit is 45 mph and there is only a distance less than 10 miles from one end of our town to the other. In other words, if we are pulling into our driveway and the message comes on, we are to not stop the truck and drive it for an additional 20 miles at 50 or more mph to complete the cycle. Video of one incident of the severe shaking is available if needed. 2. Hard washboard bouncing effect when operating vehicle at 45 mph. Went to the personal expense of ruling out tire issue. Cannot maintain vehicle at 45 mph.
