Pretty much, but it is a straight connector rather than a 90 and a longer hose. For some reason there appear to be more options on amazon.ca than I can get to come up on amazon.com (strange - American site always has more options!) Basically it is the Camco 59103, but the hose is longer.
But this does not use the QC at all, provides full pressure to the Coleman through the throwaway (1lb) connector. The QC will provide reduced (regulated) pressure to the grill; not sure if this would cause any performance issues with the grill? I like it because the grill is away from the TT and the awning.
Reading along here though it does give me some good ideas about how I can rig up an outdoor stove to put on the side rail. Next summer's project will be to rig a shelf to fit the rail, cut away a section and then add the same stove and heat shield cover that gets used on the pup in/out models. I like this, because I can make the wings a bit wider which was a problem with our pup model.
