What type of manufactured homes are transported on flatbed trucks and lack axles?

The correct choice is modular homes because they are constructed in sections in a factory setting and then transported to a building site, where they are assembled. Unlike mobile homes, which can be moved regularly and typically have axles for transportation, modular homes are designed to be permanent structures once placed on a foundation. They lack axles because they are not intended to be moved after their initial setup, distinguishing them from mobile and manufactured homes that retain some mobility features. This assembly approach allows modular homes to meet local building codes and zoning regulations more rigorously than their mobile counterparts.

While mobile homes, manufactured homes, and pre-fabricated homes have distinct characteristics, they maintain transport features such as axles that allow for movement, whereas modular homes are built for stability and permanence after their transportation and assembly.
