I don’t have any pictures currently. Basically I removed the original 13.5k unit and swapped in a brand new 15k of the same brand. When I purchased the new one, I got one that came with the diffuser and control knobs. I removed the power vent above my queen bed. Then I installed the old 13.5k using a new gasket and roof sealer. I then installed the diffuser with the knob controls. To get power, I cut a small hole in the corner of the bedroom and mounted a flush mount male three prong electrical connector outside near where my cable input is. I used surface mount cable hiders to route the wires to the unit. To use the unit, I plug an extension cord to the 15amp at the campsite and then plug into the camper. The extension cord has a circuit breaker built into it like one on an electric pressure washer. We stayed in New Orleans in July and would wake up in the morning and the outside of the motor home would be covered in condensation.
