After I posted the above I found this in a Q&A on etrailer.com (https://www.etrailer.com/question-299982.html)
In spite of what this says below, I don't think this will work. Has anyone used this?
Question:
Hello, I have a smoke hallow 205 table top grill with the regulator throw away propane bottles. My question is can I put the 277 grill quick connect on my 205 smoke hallow? And if I can where can I order one? Thanks!,

It sounds like you need MB Sturgis Quick Disconnect Propane Hose # 100476-120-MBS. One end goes into a female quick disconnect on the RV/trailer. The other end is a Male #600 (1"-20) disposable cylinder port that lets you hook up a small appliance or propane tree. This way you can power a grill, heater, or other accessory without needing to use a 1-lb throwaway cylinder.
