The RV's brakes caught fire near 14: PA 316 - Wayne Avenue around 2:27 p.m. on Oct. 25, Pennsylvania Department of Transportation Fritzi Schreffler explained.
The fire quickly spread causing "about a mile's worth of brush fires," she said noting that the "RV was pulling a vehicle and they (were both) fully engulfed in flames."
