There is no place in the country that I am aware of that requires plywood covering a manufactured homes belly board... AKA vapor barrier.

What wold be the point of adding any type of board, heavy or light to the bottom of your manufactured home? There will be a time when you need to do repairs or maintenance on the electric plumbing or ventilation system built into the floor system.

I never thought about the fire rating of foam board before so I did a little reading on line and found this

The HBCD fire retardant in polystyrenes is now the target of high concern globally. This persistent, bioaccumulative, and toxic chemical is associated with hormone disruption and reproductive disorders and is one of the top sixteen chemicals being studied for elimination .......

Avoid the toxic foam boards entirely - Use a blanket or batt insulation that does not require halogenated flame retardants where possible.

You can accomplish your goal by skirting your home with one of the cast concrete products available. See
