I found this while looking for switches:
https://www.amazon.com/dp/B0784QTL47/ref=sspa_dk_detail_3?psc=1
Size: 61x45x31mm
It has a temp probe on a wire, and the unit is everything but the fan and battery. It can be mounted inside, by the fridge, and controlled there, but the probe routed to where you need to measure temp.
Seems easier than the temp switch wired to an on/off switch which still has to be routed through to inside of camper…
Anyone use this?
(not looking for opinions of those who up til this point have never seen it…)
