I guess it depends on how fast you want to get rid of the odor. If you open some windows and take your motorhome out for an hour's drive that should change the air out in the living quarters. There are de-oderizer products to put on carpeting before vacuuming. And you can wash the hard surfaces like counter tops.
Fire repair outfits used to fog in something that had no distinct odor of it's own, just kind of a sweet sugar like smell. They would fog it in, lock things up for an hour or so, and then draw the air out with fans. A house could be full of soot, but smell as fresh as the out-of-doors. But I cannot seem to find anything like that online.
