One half of my mobile home electrical won't work
Many times when breakers trip they are hard to visually see since the handle may not move much. Make sure you shut all the breakers all the way off and then turn them back on. Don't forget the main.

You may have blown a fuse in the main disconnect seeing the mobile home and now you are only getting have the transformer or one leg of it. That would be the thing to check after resetting all the breakers.
