Get a Yearly Inspection
Your RV should be inspected yearly by a propane gas supplier or RV dealer to make sure there are no leaks or damage to the gas line.
Inspect your Propane Appliances
You should also have the tech check your fridge and any other propane appliances inside your RV.
Install Properly and Identify
You should have a way to identify the presence of a propane tank if your tank is hidden. ASME-identified tanks should be installed horizontally, and DOT-identified cylinders are installed vertically.
Replace Damaged Tanks
If you have a damaged tank, including dents and rust, or damage to a hose, you should replace your tank.
Since the late 1980s, tanks with capacities of 40 lbs. and less have an overfilling protection device, or OPD. If you have an older tank, have an OPD installed. Don't fill your tank with the RV running, or with anyone in it, if you are filling the tank while still attached to the RV.
Detecting a Leak
If you think you have a leak or smell gas, everyone needs to get out of the RV quickly. Leave the door open to your RV and shut off the supply valve.
