Officials are still trying to figure out how an unoccupied motorhome at a Sister Bay campground went up in flames Thursday afternoon.

The Sister Bay/Liberty Grove Fire Department was dispatched to the Aqualand Campground on County Q in Sister Bay just after 1 p.m. on Friday afternoon. After arriving at the scene himself and finding the motorhome fully engulfed, Ephraim Fire Chief Justin MacDonald called for mutual aid from his department to support the effort. Both departments aggressively attacked the fire to knock down the flames. MacDonald says the direction of the wind helped their actions as they were able to put out the fire with only a few trees getting scorched in addition to the motorhome. Approximately 2,800 gallons of water were used to put out the fire, which completely destroyed the motorhome. There were no injuries and firefighters were able to clear the scene by 2:30 p.m. Its’ owners are from the Green Bay area and they are meeting with investigators to determine what may have caused the fire and how to remove it from the campground.

MacDonald says the campground will operate normally this weekend as officials finish their investigation.
