Yes, you can add a basement under the mobile home.
However, you should consult with an engineer before doing so to make sure your home can handle the additional weight (which will be around 4-5 tons) and to make sure the soil around your mobile home won’t cause settling or heaving issues.
If you plan to add one using your existing mobile home make sure that the floor joists are around 6″ above grade, otherwise you will need at least 6-1/2″ of compacted gravel to provide the right amount of drainage.
The floor joists will need to be doubled up in some places and new ones added if they are not sturdy enough to support a basement.
