I found this little blister packaged indoor/outdoor thermometer/clock at the local auto parts store for about $10. The finish closely matched the bezel of my
Escape 19's Dometic
Fridge.
It has a switch for indoor and outdoor temperature or clock display at right and a small pushbutton lamp button for the backlight.
It comes with a remote temp sensor on about 6' of fine wire, which I ran into the
fridge and left most of it coiled up in a small bundle on the top shelf.

Matt
