YES! I was a TV journalist in the midwest and California for ten years, 
and I covered several terrible RV explosions and fires. Many deaths and 
terrible burns. It does happen! One time a guy opened the door of his 
camper and while entering turned on a light. His mangled remains were 
found about 50 yards from the camper.
