Help insulating and sheathing underside of a camp on pilings

I need to spray insulate beneath my camp and put up some metal or other sheathing. Have some PVC piping to work around. Don't want to mess with vinyl siding bc of storms. Anyone have experience and want to give suggestions?

if you completely close it in, it will create mold and mildew
you can cover it but be sure to leave gaps for free airflow so it cant hold moisture
i looked into foam for under my house but was warned about all the mold issues if i closed it in, so i just used netting and regular bat insulation and then left 2" gaps between the foam board sheets i put under the floor rafters for free air movement.
im very happy with it and the money i saved not going with foam

Used to own an insulation company.
The best under home insulation is closed cell spray foam at least 2 inches. Closed cell foam is waterproof. Make sure underneath of home is under 15 on a moisture meter before spraying. Closed cell will insulate the pipes and seal the underside. It will prevent moisture issues. You can then paint it or cover it.

Our neighbors did that. Termites got into the insulation and ate up the subfloor of his house. Might want to check under there from time to time.
