Yes, there is an outlet below the bottom bunk near the floor. There are outlets under the dinette table, behind the sofa, underneath each side of the master bed, one by the front door and one in the bathroom. oh, yes, there is one outside as well by the front door.
I can't speak to any provisions for a tv mount in the rear bunk area but there is one in the master bedroom just above the other outlet I forgot to mention.
We love our 28DSBH btw.
