Most of the work here has to be done by a licensed propane company. The connection to your RV is easy as soon as you put a wire in the ground. The trick is, it has two connections. Most people will use all these parts and hoses already installed is the trick to use! Check with your local propane company, but since the trainer has a regulator and if you connect a pound bottle that is considered a high-pressure port, you will need a wire that will be brought to the bus. You can see below, we have a barrel and installed at the back of the garage with a gas quick connector for easy installation and removal. You can also see that the port has a local shut-off valve.
