If you can find an old mobil home with the two bedrooms in the center that were separated by a folding wall, you could certainly set up a long arm quilting frame in that. If the two bedrooms are in the center of the mobil home and not a supporting wall, you could take out the center wall. Most of those had huge closets in both bedrooms located in the ends which would be wonderful for storing fabric and supplies. In Nebraska the Geer company made some very sturdy ones. (They are now out of business but if you can find one they are old and cheap).
