I had my local propane dealer make me one and a 25 foot hose. It works well. When finished I turn the fuel off at the tank and let the remaining fuel burn off before disconnecting. I stored my line in the compartment in the rear of the coach and the odor of the fuel is evident each time I open the compartment door. I even taped over the ends before I put it inside to prevent any dirt or spider contamination that would clog the hose. I have the BBQ stored under the dinette but that hasn't been an issue. Maybe because the BBQ is in a plastic bag?
