Save the hose/regulator off the grill and keep it on board for a backup if you ever want to switch back to a portable setup for some reason.
I don't have a quick connect adapter on my rig so it sounds like that's all I need to get for my rig, besides the Weber 6501 Adapter Hose for Weber Q-Series for the grill.
