Believe me I know all about RV accidents. No blowout involved and it was not my fault, but I was unable to control as soon as a shoulder was involved. I also did not hit my brakes. My dad who was a professional driver, (he taught cops how to avoid collisions) also drilled into me not to hit my brakes if there was any chance of driving out of a situation. Here is a photo and my dashcam video from mine a bit over a year ago. The accident happened in Canada. Note the speed on dash cam is in KPH, not MPH, i was doing the speed limit.
