We had in-laws staying in our 36ESTK3 last winter for a couple of weeks when the temps were in the low 20's at night and low 30's during the day. They were going through 40# of propane every 3-4 days. This was without using any kind of suplemental electric heat. I dol not remember what the thermostat was set on but the inside temperature was comfortable. Your thermostat setting will of course have an impact on the propane burn rate.
