Propane tank inside or outside of RV?

I'm taking my class C (27') up to the mountains this weekend where there will be no electrical hookups. I'm using my recently purchased Camco Wave 6 cat heater. On previous trips, I cracked a window and ran the propane hose outside to a 20 lb propane tank. But recently, started having problems with regulator freezing on the tank that I suspect was cutting off gas to the Wave 6 heater.

Can you all remind me what the risks are of keeping the tank inside the RV? Is it a gas leak issue, explosive issue? I've seen some folks build a small compartment for the propane tank and keep it inside.

Thanks all!

  • Got it. Well I'll stick with my outside 20lb tank powering the Olympian Wave 6 in the RV and see how this weekend goes. I definitely can't rely on the RV furnace as it takes too much from the house battery.
  • Frost on the outside of the cylinder or the regulator is not "freezing up". The cylinder will have a reduced temperature as the propane turns to vapor in the cylinder and again expands within the regulator.

    I suspect you were just low on propane and the vaporization was slowing down. The warm water would have increased the rate of vaporization. May also have some Butane in the mix that does not vaporize very well at low temperatures.
  • Thanks for the explanation. I had this problem dry camping at Mt Baker in January where the 20lb propane tank appeared to be freezing up then the regulator freezing up, then the gas fire started to go out. Until we poured hot water on the regulator and the fire came back. Inside the RV, the Wave 6 was putting out heat but pretty minimally so I suspected (but didn't confirm) the same thing was happening with freezing regulators.

    Looking at this article, I wonder if how I transported or stored the propane tank could have caused this.

  • No not advisable at all. People store them inside, some may use them, but i wouldn't. Whats up with the propane regulater? And how cold does it get? I dont think a regulater should freeze from the cold. In fact the house we used to have in lake george had an above ground propane tank, it worked fine. And it was cold there. Maybe you need a new regulater, or have another problem. Did the propane shut off or the heater? If you dont have enough make up air the unit will shut down. This is so you dont die from co or lack of oxygen. Likewise thats why its not a good idea to store or use propane inside. If it leaks or tips over and the head breaks , propane expands like 270 times displacing the oxygen in the area.

  • Thank you for that explanation. So if I want to connect it propane inside (without linking it to the RV propane) - I could connect it to the 1 lb small canister?
