Depends on what side of the trailer your AC/DC power center is on. They could go virtually anywhere there is space, like under one of the rear twins, under the couch on the front street side or under one of the dinette banquettes. There is no need for ventilation as a lithium does not produce any type of gassing like a lead based battery system.
