I just got a 'newtome' 1966
Overlander. It has the original furnace, and I have a couple of questions.
1. It only wants to operate on the 12V
switch position. After thinking about it and studying the owners manual, I came to the conclusion this is probably correct. I am guessing in the Airstream application, it works only on 12v
like the lights and depends on the inverter to keep the battery charged with city power. Is this the case? Or should it operate with the toggle switch in the 115v position?
2. The owners manual (yep, came with it) says the floor registers are for return air only. However, warm air comes out of them when it is in operation, and the return air goes in the big vent under the sink. What's up here?
