I have seen cabins where bears broke in, usually through a door completely wrecked the place in every room, ate any food thy found and defecated all over the floors and the beds and when they decided to leave, they crashed through a window. You mentioned your grill, that is another favorite target because it smells so good to them. Many of these places were places where the owners fed bears when they were in camp and the bears showed up, When the bears showed up and the owners were not there they simply helped themselves and it was not pretty.
