We have a 40 ft motorhome, with no slide outs. Right now, my generator isn't working, so I don't take my sewing machine with me. Once I get a new generator (bottom of the list, right now though as other things are taking priority) I may take my sewing machine. We usually go out in the boonies to go camping, (my hubby is not a crowd lover), and so I would have to take my own tables and stuff, but I think we would have room. Right now, I take things I am piecing by hand, crocheting, and embroidery that I can work on at any time. The first time my mother in law went with us, she was surprised at what I had to work on, but she also knows that I like to stay busy. If I am hand quilting a quilt, and I put it in a hoop, I will usually take that with us as well.
