This is what you get with the generator for running off propane.

First remove the standard propane high to low pressure regulator. We will run off the RV propane system after the RV regulator .

Now using the yellow propane tape install the adapter and RV propane quick connect fitting.

Two videos showing generator running off RV propane quick connect system. Second video is running Coleman Mach III 15k air conditioner on eco mode at 6200 feet altitude.
