Company 55 Fire Police were requested to detour traffic on Rt. 741 Millersville Rd due to the roadway being blocked at the entrance to the Outdoor World Circle M campground. Fire Police from 60 West Willow and 66 Lancaster Township were also requested to assist. Chief 55 arrived finding a travel trailer that was hung up on an embankment and completely blocking the roadway. RE 55-1 was added on to the incident to provide stabilization lighting and spill control. 55 crew assisted the tow company with rigging the RV and clean up of oil as the operator tore open his oil pan on a rock after missing the driveway. A large wrecker was brought in to place the RV back onto the roadway and remove it from the scene. 741 was closed about two hours during this incident.
