AVION Travel Trailers

It’s the “pulling it out” part I’m dragging my heals about.
It’s a suburban furnace.

I hear ya. When I installed my new furnace (Suburban), I set it up so it’d be as easy as possible to remove. I cut the cage around the part that encloses the LP pipe, as well as added a shut off. So now it’s just a matter of disconnecting the flare fitting for the LP, disconnecting the wiring harness, and removing two screws to release the front cover so the unit can be pulled out.

Fridge: Originally, the fridge on mine (1987 34V) was a 3 way. Hence a direct feed from the converter, unfused, on 8 gauge wire to the command center. Here it is (was) bridged to the batteries via the kill switch and fused for 30 Amps. The fridge was replaced by a previous owner to a 2 way and the 12VDC draw is less than 3 amps.
The Water heater: power for the water heater is run through a switch on the command center and on mine was unfused and tapped into that 8 gauge bridge in the command center. Whether there was a fuse at the original water heater is unknown to me, since the trailer was purchased with a Precision water heater, which has since been replaced with a Precision 550RV. My control center panel has been altered (by me) and the water heater, sensors and fridge are now appropriately fused for their respective current draws. I haven't sussed out the Suburban 34NT heater power other than to correct the thermostat wiring and replace the thermostat. What I found here was 12VDC being routed through the thermostat that turned on the heater. I haven't measured the current draw or traced the 12VDC circuit.

If it is a Dometic, then 12VDC is required for the fridge to operate regardless if it is 2 way or 3 way. Unsure about Norcold

Our Norcold N841 must have 12VDC for the panel. Interior light (which also powers our Fridge Fix fans) needs 12VDC, too.
