No one can predict what the changes would be.

More importantly, you should be giving consideration to the following:

What state is this happening in?

If you haven't already seen a copy of the trust, you should ask your mother to let you see a copy of it. That is your right as a beneficiary. You also have the right to annual accounting statements from the trust, but your request to your mother should be in writing or have your trust attorney make the request for you.

Ask your mother who the successor trustee is, if something unexpected (death or severe illness or mental incapacity) happened to her.
