If you’re hooking up a bbq that normally hooks up to a propane tank you will need to do a couple things. First you’ll need to get a gas hose with a low pressure quick disconnect fitting on it to replace the hose on your bbq. You should be able pick one up from make up and sell propane hoses and fittings. You can also pick one up from an rv parts department or amazon. You should be able to pick one up for $20 or less. Take the hose with the regulator off your bbq and put on your new hose. Use some Teflon tale and/or liquid Teflon on the threads. I like to use both. If you use liquid Teflon use a light coat. You don’t want it to get into the gas line. You can then put the hose connector into the connector on the trailer. Behind the connector on the trailer will be a valve, turn it on and check for leaks. If all is good fire up the bbq and start cooking. When not in use I like to turn off the valve behind the connector on the trailer.
I know the voices in my head arenít real, but man, do they ever come up with some great ideas.
