You likely now have space for a washer/dryer and plenty of closet space. If you are really handy it could also become a 1/2 bath. I suspect you are only limited by your imagination!
We bought our mh with the intent of taking our great nephew camping or on trips. Thus far after 5 years only a couple of times. We use the space as is for extra storage, overflow for DW’s clothes, shoes, whatever. This way if he wants to go, we still have the bed.
