A locker is a relatively easy build on most buses. You just need to make sure it vents dawn and out without any restriction. Expanded metal makes for a good bottom. A few air holes up high help move any fumes out as well.



Being heavier than air, you really need to make sure it cannot pool and collect in a closed space and certainly NOT one inside the bus.

Yeah I know the 5 pounders are small and not terribly convenient, but then again we're not using much propane - just for quickie showers and cooking, primarily. If I could find a way to put a 20 pounder outside without it sitting too low, I'd like to, but just don't know if there's a spot that'll work on the short bus.

Tango, a locker put inside the bus like what you mentioned, sealed other than the bottom with vents down through the floor, is still a big no no, I take it?

It has been done and successfully. But it must be absolutely sealed to the interior and very open to the exterior. Remember that once you are rolling down the road, it can be easy for air pressure to force any gas back into the cab. A well designed locker will use any such air to clear the locker rather than pressurize it.

Thanks! That may be my answer then. Properly angling louvers (or otherwise) below the locker to suck air and cause lower pressure inside the locker would be one way to do that, not difficult, and would be worth the effort in my opinion. I have a friend who can fabricate something pretty easily if need be.

Well, before I started thinking bumper my plan was to mount a cage over one of the small back windows on either side of the back door and house a propane tank there. Then someone pointed out how easy it would be for a person walking to the back door to smack their head and knock themselves out by crashing into the propane cage, which would be about head height for most people. But I would think it would at least be DOT legal because it wouldn't be in direct bumper-to-bumper line. Maybe if it were painted fluorescent orange, or padded, no one would get killed.

I have seen 20 pounders that lay on their side. Would only be 12 inches deep. they can be oriented only one way. I am pretty sure they will be marked as to which side must be up during use.

the outlet would need to be upwards, otherwise the hose would fill with liquid propane ?

The valve on these bottles have a curved dip tube that angles to one side so as to draw vapor only when that side is up. The UP side should be clearly marked by the assembler. It all depends on where that dip tube ends up when the valve becomes tight.

What do you think about this?

I've been trying to come up with a way to do my rear-window propane storage "cage" seeing how I don't weld and don't have access to anyone who welds. In my quest for the low tech solution I can do myself i came across what looks like an option, but I don't really know if it's workable.

Do you think a bracket like this:
https://www.amazon.com/Nashfuel-Univ...gateway&sr=8-1

Could be bolted on the back of the bus - over the spot where the little side window now is? (see image)

And then covered with something like this:
https://www.campingworld.com/heavy-d...lack?rrec=true

Would that be a safe, acceptable solution? I'm probably not looking to connect it from there to anywhere else, I would use it to refill smaller bottles (the legally refillable ones, not the little green one pounders).

looks like it would work fine to me
