In order to be able to use propane appliances on the outside of your Class A motor home you could install an extended stay kit to your LP tank. This allows you to run your barbecue grill or propane cylinder without using the propane from your LP tank.

You will need two 7/8’ wrenches. Using the 7/8” wrench you will loosen the regulator assembly and move it out of the way. Since this is a gas appliance it will have left hand threads. For $45 you can purchase and add a T fitting to the gas tank. Tighten the gas fitting with the 7/8” wrench being sure that you set the T fitting so that your tubing can reach the valves. The fittings are one way so you can’t make a mistake with the attachments. Be sure to check for leaks by spraying soapy water in a spray bottle around all the fittings. If you see bubbles you need to tighten some more.

You will need a second wrench (one for holding and one for twisting) to put the hose on that connects your grill to the T fitting.  When you are ready to connect the hose to the cylinder it is best to connect to the T fitting first because you will need to twist the tubing to until it is tight enough. Then connect to the propane cylinder. Always remember to check for leaks by spraying all the connected parts with the soapy water and then look for bubbles. If you find any bubbles than you need to do some tightening.
