When insulating a tiny house on wheels you need to remember that you will be bouncing down the highway with it, so anything in terms of insulation and even air barriers should be chosen and installed with that added stress in mind. So I would avoid things like spray foam, and your suggestion of Rockwool (formerly known as Roxul and technically called mineral wool) insulation is a good one. Here is a page to the best Tiny house we've seen, and it was insulated with Roxul batts, more than we have seen before -
