The company that figures out how to make decent quality housing that fits on the back of an 18 wheeler that can be picked up and moved along with the job will be wealthy.
It would ideally be better than the crappy cheap trailer homes of today, as mobile as an RV and - if the company provides the housing and moves it with the work - a big incentive to potential employees.
I might even take it a step farther. Most of what we’re seeing here is what everybody is calling Man Camps, small portable housing or travel trailers. I’d put in a centeral dining area and a small store. These Men are working long hour’s and multiple shifts, make it as easy on them as possible.

Even a mom & pop landowner that could afford to bring in one container at a time would do.
Haul the container in, rehab for residential use (doors, windows, plumbing, electric, HVAC, insulation, etc), add more over time.
