Results of the cooling unit replacement...
Thermistor attached, on propane: About 40F
Thermistor attached, on AC: About 36F
Colder with the thermistor discconnected. Is the 2 year old thermistor bad?

I was going to get a Camco but there are reports of very dangerous defects:
"I purchased this from Amazon to use on our toy hauler, it looked good and reviews seemed to be ok at the time. However I installed it and used it one time on a trip to the mountains. The second time we used the toy hauler I started smelling propane, a lot of propane. When I tracked the smell down I found that the regulator was leaking from the crimped seal on the outlet side of the regulator??? I'm glad I noticed this before a major problem occurred, ie EXPLOSION OR DEATH. I have used regulators for years on various things, however to have one fail like this after just a few months on the RV is scary!!"
Camco on Amazon
Camco early failure
I found this alternative. Made in USA and seems very good. We shall see.

Tank connection is reverse thread
Used yellow Teflon tape
Does not quite fit level, so turned it slightly
Checked for leaks with soapy water
Results at home (6000 ft) and 70F
After replacing propane regulator...
Setting on max cold
On propane: 36F, 8F freezer
On AC: 35F, 8F freezer
So, problem solved? Not yet.
