What is a "stay-a-while"??
These go by a number of names, another popular one is extend-a-stay
It is a brass combo valve assembly that goes between the propane tank and the RV's propane regulator. They allow you to use an external portable propane tank to supply propane to your RV, they can also be used to operate a BBQ grill from the RV's propane tank / tanks.
This is the one I installed after a valve on the old one on my motorhome developed a slow leak

I think I bought mine from Amazon
