Last night at 2220 hours, units from Landover Rd. were dispatched to the 1800 Blk of Elmwood Park Dr. for the report of a mobile home on fire on Box 37-06. #Engine332 as the 4th due engine, #Truck33 as the first truck, and #Chief33. Engine Co. 23 arrived to a 1-story trailer with a shed on fire in the rear and extension to the exterior. Engine 332 established RIT. TK33 completed secondary searches and opened up to find no extension to the interior. The run was quickly scaled back to 2-2. Units from 33 operated for approximately 30 minutes before returning.
