A recreational vehicle air conditioner (RVAC) includes a ceiling-mount indoor panel positioned over an opening in the ceiling of a recreational vehicle and a control box assembly including a first box portion and a second box portion. The first box portion is positioned above the ceiling-mount indoor panel and the second box portion is pivotally connected to the first box portion with a hinge, such that it is pivotable between a closed configuration and an open configuration. The ceiling-mount indoor panel defines a control box recess that at least partially receives the second box portion when in the open configuration and a blank plate covers the control box recess when the second box portion is in the closed configuration.
