Two sections built to go together
In this picture you can see the seam that goes down the middle of the home - this is very typical of older mobile homes. New models are now made to hide this seam, as in this picture below.
Same Two Section Construction
A nice new model Building Mobile and Manufactured Homes this way makes it easy to transport and install the sections.
Sizes and dimensions:
There are many Mobile Home Manufacturers and each will have slightly different styles, shapes, and sizes. In general, double wide Mobile Homes sections come in these dimensions: 10 feet, 12 feet, 14 feet, and 16 feet wide 42 feet to 67 feet long This does not include any porches, awnings, covered parking, sheds, additions, etc. So, a double wide can be from 840 sqft to 1876 sqft. Of course these are general numbers and actually many Mobile Homes can be ordered from the factories with adjustments made to the size over all. Resource: Free Mobile Home Info
