Yes, I converted all my appliances (BBQ, firepit, etc) to run off the RV system.
Very easy to do but you must remove the items regulator. All I have seen are attached with a simple NPT fitting and I simply adapted a male quick disconnect to them. Then I made up extension hoses.
You could skip the extensions and just connect the rubber line to the BBQ. Ebay has many of them.
I did all this because there was no safe or convenient way for me to carry a cylinder.
This pic may be confusing but after removing the reg, I was left with an 1/8" male NPT. I could have used an adapter fitting to convert that to the male quick disconnect but I just tapped the inside of the QD to accept the 1/8NPT.
The conversion on my fire pit:
I have two 10' hoses and one 5' hose'. I can use one or all of them.
I also made a hose that has the BBQ's regulator (because it has the highest flow and will work for anything) on one end and a quick disconnect on the other. Using that, I can still run any of my modified appliances off a bulk cyl.
I have about $100 wrapped up in all the hoses and fittings.
