I lived in an RV for 3 years when I was taking care of my FIL. I kicked one of the easy chairs to the curb and set up a card table I'd had a friend fix up so my machine sat down in it. Kicked the TV to the curb and had a huge open space left. Had 4 corner boards (legs) cut and a shelf board so I then had two really nice shelving units shelves. Nails in the wall above the sewing machine for rulers.
All that is behind me now, and my new love is my hand crank I take when Rob goes fishing. W/base, about 13 pounds
