A fresh horse.....
Fire or explosion is not the only concern with a gasoline spill next to your MH. A diesel engine operating in heavy gasoline fumes (or propane gas) can runaway. The engine can accelerate uncontrolled until it comes apart. Diesel engines have no throttle plate, or ignition to turn off. Diesel engines operating in oil fields or tank farms are required to have an air intake shutoff. The only way to stop the runaway is to block the intake.
BUT: Most motorhome air intakes are on the roofline for this reason, unlikely that fumes in sufficient concentration could be ingested...
