How Long Do Your Propane Tanks Last
I am going out this weekend for a 2 days of dry camping and was wondering how long the two propane tanks will last since there is not a gauge on the tanks. I bought my TT at the end of last year and ...

They last right up until they run out.
No, really, it depends on the weather. If you are running the furnace, that'll run 'em down fast. In the heat of summer when the only draw on them is the fridge and cooking, two 20 pounders will last for months. In the dead of winter when the furnace is going great guns as well, you'll get perhaps a week out of each tank. And that depends on where you set the thermostat.
Any closer than that is impossible to predict. I note that I have a non-thermostatically controlled Mr. Heater device that is rated 18,000 btus, same as the furnace in my TT. You turn Mr. Heater on, and he runs continuously, and will suck a 20 lb tank dry in 18 hours, according to the chart that came with it. That's 36 hours for two 20 pounders. Fortunately, your furnace won't run continuously unless it is REALLY REALLY cold, so take day-and-a-half as the limit on that end; anything longer is easily within the realm of possibility.
