After getting our DirecTV Trav’Ler dish installed and set up for multi-tv use, the AV “closet” in the Allegro 31SA was a spider’s web HDMI switches, power supplies and cables. This has led to previous complaints of failed HDMI switches due to overheating. Additionally, due to the limited HDMI port availability and space constraints on the coach TVs, it is difficult to add the kid’s gaming console for them to enjoy while driving or parked.

With that I had two objectives for this mod:

  1. Improve the airflow within the small space to reduce heat further
  2. Add ability to easily plug in gaming consoles to play on any TV within the coach.

Neither job is overly complicated but you must be comfortable with cutting into your coach cabinetry if you want to achieve the same result.

The end result came out well and the DW is very satisfied with the clean look and ease of plugging systems up.
