Mdk,
You are welcome, and it sounds like you have everything up and going Great!
Now to your T-stat and what kind you have

Great stuff! That's exactly what I'm looking at lol. I had the 2 capacitor setup. I do not have a digital display like yours. Just a few switches that change from on, auto for fan control, temp control and a setting for cool, off and heat.
Opps...:S. OK, let's try this again.
The T-stat shown in this picture is the cream-colored rectangular-shaped bottom device that says, "Duo-Therm by Domitic". This vintage is the analog-style T stat that works with the analog control box. This control box requires a separate 12 VDC source run to the control box to operate the controls. The camper 12-volt DC system provides this. The 120 VAC is fed to that box, but it only powers the motors on the roof unit.
The digital display above the T-stat with the word (Acu-rite) is a 2, AAA battery-operated remote thermometer. I have the remote sensor inside the fridge to tell what temp the fridge is doing without opening the door. It is 34.7 F inside the refrigerator. The 70.4 F is the ambient temp in the room. This display has nothing to do with the AC unit or the furnace. LOL.... sorry about that; it just came along in the pic.
I hunted down a pic of the vintage before the analog control T-stat. This is called the "Bi-metal" system. This pic shows the T-stat that works with the Bi-metal control box. This bi-metal control box only had 120 VAC come to the control box up in the ceiling. An onboard transformer created the control voltage to work with the T-stat and power the control board to turn the relays on and off to control the roof unit. This system has no short cycle protection; you are supposed to wait and not fiddle with the on/off buttons or the temp slider. In automatic, the system takes care of itself. The two vintages of the system cannot interchange T stat or control boxes. They are specific to the technology of the time.
OK, now curious as I am "into" the Sunline brand of camper, what T stat is in your 2003 model year camper? And you know what month and year it was manufactured? This info is in the binder manual or the VIN tag on the front left outside of the camper if you can still read the tag. The model years rolled mid-year, sort of like the car industry.
Have a good campout,
John
