I tried to use the propane line for cooking (located in the compartment to the right of the entry door of the motor home). I purchased the proper hose to connect from the line to my cooking grill. When I turned the line on, I barely got enough propane to light my grill. Since I was connected to the grill thru a propane regulator, I was wondering if the line is now seeing a "double" regulation, thus prohibiting the flow of propane to the grill. I have a 2018 forest river legacy, and there is no documentation discussing this propane line.
