Dry camping with furnace on

In addition to the above info, one can add insulation to retain heat and thus run the furnace less. We have insulated window covers that snap over all the windows and a cab curtain that completely isolated the cab walls from the house (truck cab insulation sucks).

We also converted to LED lighting.

I have a multi stage power converter which charges faster than a single stage converter.

I have two AGM deep cycle batteries which can accept a charge faster than flooded batteries.

First thing in the morning I crank up a generator and start charging. I also may crank up again at dinner time depending on how the batteries are doing.

I use a Buddy Heater while we are awake.

We turn down the heat at night.

I drink single malt Scotch. Wife likes Irish.

Here is where you can see our insulation setup on two RVs we did.
