I bought a Weber Q 2200, to go in our new 22RBPR and the coach has an external gas port for the outdoor kitchen.
I modified the gas line, with a "T" and added a second quick connect, modified the Weber with a quick connect and got a 10 foot quick connect hose from Amazon.
I also got the optional griddle for the Weber and the only "cooking" so far inside the coach was a pan of nachos in the oven.
I love the Weber, it does a fantastic job on steaks. I have not used the griddle yet but I see pancakes in my future
