Hi,

It boils at -43.6 F but at -40 you won't get much vapor. I do carry a tank heater, but have never had to use it.

To expand on what's stated above, the cheap screw on gauges are absolutely worthless. Propane is stored under pressure as a liquid and it boils off at -22f creating the pressurized gas at the top of the tank.

Only one is going to go empty at a time.
When Indicator goes from GREEN to RED.....swap indicator lever to other cylinder
Then remove the empty one and go get it refilled.

TWO 30# cylinders (14 gallons) will last a long time

FTng we went 6 weeks on ONE 30#

Pressure inside cyliders doesn't change a lot until almost empty
Overthinking the issue.


We've been using this method for 10 years now, works GREAT for us! One tank valve open, one closed. When tank "A" is empty switch to tank "B" and when it's convienent, get tank "A" refilled. Old Biscuit is spot on!! 30# tank will last a good long time unless you're running the "h" out of your furnace! [emoticon]

Old Biscuit has it right both tanks on when the indicator changes to RED flip the leaver to the now in use tank, and take the other to be filled. Had tanks filled while camping many times.
To the poster with the slide out tray, we had one on our King of the Road, loved that setup! The tray was full extension PLUS about 2” dry easy to pull the back tank.
If you leave one closed and you run out at 2:00am on a cold rainy night you might change your mind, especially if in your cold wet dash to open the valve and you don’t get any propane!!

google propane and read on about its properties. Propanes boiling point is -44.3 f. At that temp there is no pressure at all, you could pour it out and carry it in a bucket. OH ive done that in Ontario at -50 f.
Pressuse gauges are of no use, because at any given temp. they will show the pressure developed by the liquid as it boils to vapor at that temp. So at -43f it would show empty on a full bottle, yet at + 90f show full on an almost empty. .They cannot show the liquid level.
, only float gauges can tell you the liquid level in a bottle. Motor homes have them that show 1/4-1/2 -3/4. Acommon issue with them is that if 80% is full, then they should read more like 1/3-2/3-3/3 which more closely is the liquid level.
The hot or cold water test ( use one or the other depending on the ambient temp- hot weather use ice water, cool weather, hot water) poured down the side of the bottle then run your fingers down the bottle to feel the temp change will show you the liquid level in the bottle, as the water will heat or cool the metal only down to the liquid propane level.
Stick on heat sensative strips are very good at this test.
I have always left both valves open with the switchover valve pointed at one bottle, then kept an eye on the indicator. When it turns red, that one is empty and it has auto switched to the alternate. So then you switch the indicator to the alternate indicator turns green, then go fill the. primary, put it in open it, then the alternate is now the primary until it empties and switches to the first.

IMO, the gauge isn't to determine exactly how much propane there is, but rather to determine if you are getting low enough that it makes sense to refill now instead of waiting until you actually run out.

For that purpose, the gauges work well enough.

I have to ask why? I treat my two 7 Gallon (30#) tanks as one 14 gallon (60#) tank, when auto cutover happens it is tome to get a fill up.
Why take in a partially full tank to have filled, I personally think doing that is a waste of mine and the attendants time and effort.

How is it a waste of time - it's no different than filling your vehicle fuel tank when it's half empty. If I'm going for a short time, then I may wait to fill. But if I'm going for a couple weeks or more, I'd rather start full up then have to worry about driving a couple hours on curvy mountain roads to find a place to refill because I needed that half tank's worth.

Around here there is often a minimum. So you may pay same for 2 gallons or 7. I fill when the indicator says one cylinder is empty not before. I don't find it to be a hassle to get propane on the road. OK either way, just my style.

Around here also, many places charge by the fill, not the amount. Even our propane company charges a straight rate to fill a 20 or 30 pound tank. Amount is irrelevant.

I'd find another propane place. I've =never= seen that and, if I did, I'd just say, "not interested", and go elsewhere. F'n ripoff!
