National forests in the US face a growing problem of abandoned motorhomes and travel trailers that are hazardous and costly to clean up. The non-profit 208 cleanup helps remove waste, but derelict motorhomes require law enforcement condemnation before removal. The Boise National Forest recorded about 36 such items left on the forest over the last 12 months. Removing each can cost thousands of dollars due to hazardous materials such as batteries, refrigerant, tyres, sewage and sometimes asbestos.
