Yah, not so easy...
Short answer is that you need a temp reg on the grill... then just run a hose.
Problem is that the 'Quick Connect' is LP regulated from the camper tanks so you can't use the normal hose with a reg on it..
If you find a hose without a reg on it, then you get a quick connect end for the camper end and then screw into the Grill.
Key is if the grill has the Temp control on it... otherwise you'll have to keep adjusting the flow from the quick connect..
Hope that helps.. just don't use a hose with a regulator on it... as it's then double regulated and no pressure except like a Bic lighter...
Hope that helps, should be an easy thing, but Nooooooo... heheh...
I believe the direct hoses are easy to find, it's the grill having the controls on it that you have to look at...
Happy cooking..
