I went to Maple Leaf web site to see mini mobile homes, bigger than my 248 SF travel trailer by about 300 SF but still small and efficient...and no tanks to worry about.

Once there, I found these worker bees with the cranes. Look at photos to see this 9-unit, 3-story condominium these guys put up in a week. Imagine someone who went on vacation and then came back to work after a week and saw that complex along the same route they drive every day. They may thnk they need another vacation. Check out the web site below.

Maple Leaf has built remote mining camps, flight training schools, resort lodging, so they must be quite good at what they do. Located in New Brunswick, they also have retailers in the New England states. I would like to watch something like that condo going up.
