Dometic refir not cooling well

[Curt Sprenger]

Greg,
I agree, a good fan at the upper vent would be better. I used the adjustable
thermostat with on/off to control the fan. If I just had a switch, and it
was ON, it would be on all the time unless I remember to read my Quick
Reference card. You'll know what I mean in another 20 years.
