Our van-RV is our "home away from home". We both love it but I lack just enough room for my portable Featherweight box. I have a small plastic shoe-box-size container for hand sewing my quilt-piecing. It contains all the 'little' tools and some fabrics I'd need, incl. a small cutting mat and small rotary cutter.
So far, that has kept me happy. Iron? NO! We're on vacation and I can do that when I get home. But living in a 33' RV 5th Wheel, even with bump-outs ... I can't imagine NOT finding a place for storing equipment (even a pressing board instead of a large ironing board?) When you move again, you'll have to 'stow' the stuff, so it doesn't fly around in case of sudden stops!
Good luck and enjoy your AZ stay.
