Wow, shocking to look at for sure. It looks like it may have been a Newmar from the basement doors and latches and paint, not sure. If anyone finds any more details please post. While we can only speculate what happened I also find these RV's can get away from you in an instant from distractions in the coach whether cell phone, GPS interaction, something dropping off a counter and you want to look and see what it was, etc. These Class A's require you to be at full attention 100% of the time as you can go off the road in an instant!
Yes, inspect tires and pressures as we all have learned. Take a flashlight and look across the other side and look at the insides of the tires from time to time too. Tires are every Class A owner's nightmare and have been mine since day 1.
