On 4/22/2026 while flat towing this vehicle behind my motorhome, it burst into flames. The trip began in [XXX] . Driving south on XXX, I stopped about 120 miles later at a rest stop near XXX. I did a complete walk around inspection. There were no issues, everything looked fine. We continued on and about 20 miles later another vehicle driver was telling me frantically to pull over. I looked at my rear camera and saw the Ford was smoking. This was not due to an improper neutral tow setting. The truck would have burned in the first 20 miles. I have towed this vehicle many times. I know the importance of doing it properly., Thankfully there was a good place to pull over. I tried to extinguish the fire with my extinguisher but it was too hot. I was unable to disconnect from the motorhome. Both are a total loss. I think of all the places this could have happened and how trapped we could have been. By the grace of God, nobody was injured. Yes there is a police report and an insurance claim. There were no warning signs. My braking system runs on its own battery so there was no draw on the Ford battery. Ford did an update on the computer the night prior. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
