Typically, there is a high pressure and a low pressure regulator on your RV. The high pressure regulator feeds the water heater and furnace and the low pressure regulator feeds the stove/oven. If you can add a tee downstream of the existing high pressure regulator, you can supply your outdoor grill. This is what I did and chose to use a quick disconnect. Likewise, I placed a quick disconnect on my grill and it is a simple matter to setup the grill. I also included a valve upstream of the quick disconnect as a safety measure.
