No injuries are reported from a large RV fire at a campground in the Downeast town of Trenton.

Trenton Volunteer firefighters say they were sent to the scene at Narrows Too Campground just before 8 a.m. Tuesday.

They say everyone inside the camper was able to get out safely before crews arrived.

Fire crews from three surrounding towns – Ellsworth, Hancock, and Lamoine – were called in to assist with the fire. “Due to the size and complexity of today’s modern recreational vehicles and park model campers—which can approach the size of a commercial bus—the department activated its automatic mutual aid response,” said the Trenton Volunteer Fire Department in a statement.

The RV was significantly damaged and is no longer drivable. Staff from Narrows Too Campground were assisting the occupants with arranging alternate accommodations while recovery efforts continue.

The fire was determined to have originated from a malfunction in the recreational vehicle’s refrigeration unit.
