My 1lb propane tanks keep freezing or something that I don't get to use the full tank. So I almost need to carry 2 or 3 and keep changing them. I've raised the heater off the ice and still get the problem. It happened on a construction job too. No ice, just the wooden subfloor. Still froze. Had to switch tanks and thaw the frozen one. PITA!

I notice that on really cold days i need to shake the cans to get em flowing.
I swing the can back and forth while on the heater to swish the liquid propane around. Some days i need to do this when it gets to about 1/4 full.
I am wondering if maybe there is something in the feedline????

Is it that on the 'really cold days' the propane is starting to freeze inside the can - going through phase change liquid to solid - via slush.
By moving the can around - you could be breaking the surface skim - allowing more propane to vent off from liquid into gas? More surface area for it to slowly release gas?
That's why a larger 20lb tank - in same temperatures - doesn't have same problem as the surface area within the tank is much larger so allows more area for the gas to 'flash' from the liquid - for the same flow rate of gas . . .
If were me - I'd likely set 1 spare 1 pounder in front of heater (not on top) to heat it up a bit before attaching to buddy heater. Perhaps they need to be insulated from the outside cold with some sort of sleeve - such that if starting warm they cool only by the liquid inside flashing into gas.
Another thought to warm up a very cold tank - submerse it (attached to something) in a fishing hole. While the ice and surface are far below zero - the water is a couple or so degrees above. Just be sure that top of can is dry from water before reattaching to buddy heater . . .
Perhaps on the really cold days - if using 1 lb tanks - as an poster on an earlier thread suggested - leave at home and instead bring a naptha / white gas stove or lantern. white gas / naptha doesn't chill itself in its tank as liquid propane does. the white gas is fed into the system as liquid and freezing temperatures are even lower than propane . . .

I have to update my reply, went out fishing after three nights of -35 ,full tank outside in the flipover. Got two hours of heat and my 11 lb tank was frozen. No heat on a cold day is not good. Packed up, came home and thawed out the tank. Next day all was good again. The heater did sputter for a half hour but smoothed out after that.

Thanks for the feedback. It's nice (not really but for a lack of a better term) to know that I'm not the only one experiencing the freezing canisters. It is indeed on the really cold days. I do raise the heater off the ice and try to keep the propane warmish. Sloshing around helps too. I guess it's just the nature of the liquid propane to gas. Oh well. Heater works great when it works. Thanks again.
