Propane Tanks Inside?

Am considering building a kitchen for my Overlander with a place for a propane tank under the sink and a one or two burner cooktop. If I take all due precautions (detectors, tanks shut-off, etc), is this a safe (sane?) option? I will only be using propane for the cook-top.

No, the tanks have relief valves that can vent under certain conditions even with the valve closed. Also, the regulator is vented and can leak.

The 15 oz disposable cylinders are the largest considered safe for indoor use.

Our propane vendor won't fill a propane container for anybody who is transporting it inside a closed vehicle. It has to be in an open truck bed.

The vents on these tanks would end up leaking propane inside the AS, and could blow you to Smithereenz, which is just outside Slap Out, Alabama.

Don't fifth wheels have internal propane storage?

On fifth wheels they are in a compartment and is vented. So they aren't in the living quarters

Would not advise it at all. Propane bottles if in containers are generally very well vented.

Whilst the two 30 pounders on our AS are enclosed on the tongue, the whole bottom of the container is wide open - and propane is heavier than air.

if you do go that way its open mesh floor to allow the flammables the optimum fuel/air mixture...err... to allow the gases to drop straight out of the enclosure so no/low pooling of combustibles in a confined space.

Nope, propane cylinders must be open to air. On RVs with cylinders enclosed behind doors, you'll find that they are open to the bottom. The logic is pretty straightforward: Propane is heavier than air and will pool downward. If there's no bottom or no side, the propane will escape; otherwise, you'll facing major ugliness.

I've witnessed this before with people carrying bbq grill cylinders stored in fully enclosed motorhome storage compartments. (To make matters even far worse, they're stored horizontally.) Just waiting for a disaster to happen. If someone asks me to fill one of these time bombs, I refuse.

It's not unlike outdoor residential propane tanks: You cannot build a fence all the way around them; one side must be left open to air.

Ditto on the "No-Pro" inside the living space.

Not safe...

This made me a think of an event quite a few years ago.
I had a friend who was a Cop. Got a call about a car accident. Details were confused, he know what happened.
Turned out the guy was carrying a LP bottle in his car and lit a cig! It blew up in an intersection which really added to the confusion!

Methinks my question disproves the notion that there is no such thing as a dumb question! Many thanks to all. On to Plan B.
