Propane Tank - Laying down for transport?

It's the height in the basement of the 5th wheel that gives me issues. It just fits on it's own, I have it attached to front wall with a bungee now.

I thought that was case just wanted to confirm. I will figure out a way to carry it upright. It is for my BabyQ grill. I wish they would make the BabyQ more friendly to hook to a quick disconnect on the trailer and still be able to attach to a 20lb tank at home.

I assume you are referring to taking the propane tanks to get re-filled. I keep my propane tanks in its holder on the front trailer tongue when driving down the roadways...

When I take my tanks to a propane place for filling it is always set upright sitting in the bed of my truck and held in place with stretch cord.

Laying horizontal I would be afraid it might roll around and knock off the valve...

Beside safety it isn't good for the float valve. The next time your at an rv place where they fill cylinders, ask them and they can show you how easily the valve can be damaged internally from the liquid sloshing around. Note this is for the older style. He said they have a newer type that isnt as likely to be damaged but I don't see any way to tell which kind it is unless the valve is removed..

It should only be mounted horizontally if it is actual horizontal cylinder like used in some truck campers.

And the only inspection might occur at some tunnels/ferries where it is required to be valved out.

I have never been stopped since we started rving in '82.

Not safely.

Doing so will disable the safety mechanisms built in for your protection.

If you're just wanting to carry some backup propane, you might consider an 11-lb. vertical like this one. Same width as the twenty, under a foot tall, a little over half the capacity. Enough to give you a couple days to fill your main tanks, and easy to store. I bought one for the same purpose and it's worked very well for me.

The following is from 'propane101.com'


Position of LP Gas Cylinders In Storage

Propane cylinders should always be positioned so that their relief valve is in direct communication with the vapor space of the container. Cylinders that are stored vertically upright will have the relief valve communicating with vapor space. Regarding the cylinder relief valve, it is important to keep the safety relief valve pointed away from anything that escaping propane could come in contact with possibly causing a fire or accident. If cylinders are stored improperly, such as on their side with the relief valve in contact with propane liquid and the safety relief valve opens for any reason, liquid will be escaping instead of vapor posing a much greater danger. In short, be sure the relief valve is communicating with the vapor space of the tank. All consumer propane cylinders should be stored vertically upright in all circumstances.


A 'vertical' propane cylinder should always be vertical......filling, in use, transporting, storage

Not everyone does........you decide if risk/benefit is worth it.

Why not secure it in bed of truck?
