Mounting a Propane tank on rear ext. wall ?

Something to consider: Prior to the Alvord trip I was trying to figure out how to mount a std bbq propane tank on the Blanc-Oh's swing-away without much success. I realized that the diameter was the fitment problem. Looking around I found 2.5 gallon tanks that were either the same height and roughly half the diameter of the bbq tank; or there was one of the same diameter that was half as tall as the std bbq tank. For me the tall, skinny tank worked best.

 

I was a little concerned about capacity because we were going to be cooking two meals a day for 6 guys for the week that we were on the run. Typically we used less than 1/2 of the previous bbq tank, but I didn't have either of those vehicles that I transported it with available for this trip. Half of a bbq tank was going to put us right on the edge.

 

I forgot to factor in that we no longer use propane lanterns. I came home with the little tank still about 1/2 full. If the OP's use isn't huge then these smaller tanks might be an option. They use the same valve connection that the bbq tanks use, so they're fully interchangeable that way.

Not to spoil the fun....but....I was going to mount mine on the exterior when I did my rebuild and found out, at least here in the States, it is illegal. Must be mounted interior or to the frame.

Pretty simple to build a bracket like the Overland one.  I have a buddy who has two on his camper (one each side of the door) and it is easy to switch between tanks with a valve in the center.

Did you find this in the FMVSS somewhere? There must be some variations allowed since even new production tag travel trailers commonly have it/them mounted on the tongue.

The tongue is considered the frame. Also, mounted on the tongue they have to have cover from the elements officially, but we've all seen pop ups running around without that. I was looking last night to find it to quote specifically. I got it from my buddy who was a dealer tech and had the book. Must be mounted to the frame or in a sealed compartment is the basic verbiage it had. I wanted to mount mine external to add storage space inside. No go unfortunately. I didn't do it for liability reasons, not that I think law enforcement would pay much attention. If I got in an accident and something bad happened, well, all the insurance in the world goes out the window.

maybe i will look into a custom box that i can hang off the jack brkts

The right sized under-bed or flat bed tool box might be just the ticket. Along the lines of one of these:

I just spoke to my Propane supplier who said for a non-connected tank, the only regulation they have for transport is that it be secured and vertical (valve not flooded with liquid).  Being connected (valve open) may be the difference with location of tank.
