First question - What is the function of the 3-way rocker switch on the front panel next to the thermostat?
I'd assumed it was on the 12v circuit to source select battery-off-shore power.
But that can't be it - today I took off the front panel because I was confused... now I'm not - there is NO power converter in this camper! I'm really surprised about that; maybe I shouldn't be?
This *does* seem to explain why, with a suspected dead batt, I'm not getting shore powered lighting.
The setup appears to be this:
Shore power through a 15a breaker feeds refer outlet and gfci outlet near sink.
Battery Tender plugs into gfci outlet near sink and charges batt.
Battery connections: (batt is located passenger side rear of camper under couch)
* Two terminals exterior on passenger rear of plywood box for charging connection from the truck.
* Light wiring to defunct battery monitor on the box under the couch, visible through open door.
* Heavier (12ga?) B&W leads around the outside of the camper, re-enters driver's side forward, white (pos) leading to fuse box, black (neg) leading to terminal block.
* All 12 volt distribution then comes from fuse box and terminal block, fuses marked lights, refer, water pump, furnace, 12v outlets, (unused - rear spots).
Second question - should I install a power converter? I would typically be at a forest service campground (no services), or, a state CG (services available), or, setup someplace where power is within 100', and I do have a 12ga 100' extension.
I want to be *very* on top of power so that I always have at least 3 nights of cpap use available off 12v.
How do you balance the advantages of a power converter vs. just charging the battery with truck and AC/Battery Tender?
