Getting ready for a short weekend trip. I filled water tank to 2/3's to save weight. While watching the gauges I realized the propane was empty
AGAIN! 
I've left the furnace on the last (2) trips after we got home. That works out to about $100.00 in propane for a couple hours heat. DW not happy with me.

Maybe someone can remind me next Monday, to turn off the thermostat, though I think DW just might do that.
