I have a 2006 HR Admiral, but this probably applies to other Monaco products as well.
Two AC/heat pumps and one furnace are controlled by a single Duo-therm control, located on the curbside wall, just behind the passenger seat. This is an inconvenient place as one must reach across the lounge chair to reach the control. When the sofa bed is out one must climb over the bed to get to the control!
I decided to move the thermostat to an interior wall in the bedroom. This was really quite easy. Rather than take up space here, let me know if you are interested in how I did it and I can send you an email.
No more stumbling through the coach at night and climbing over the grandkids on the sofa bed to adjust the temp.
