If I had an RV I think I would try sewing. I would mount the sewing machine so it cant not move or fly away. I would put in a converter box so you can use a electric machine . I use a small one like a feather weight or some small machine. I would also get some band aid because u might sew your finger on bump. lol . But I think it would work. I would think if you had the machine mounted so it cant move , it would be no defiance than having a stove or refrigerator in the RV. This only my thoughts
