Two thoughts
One is addressed above.. Modern tanks have an "Excess flow" sensor that shuts off gas flow if it flows too fast.. OPEN the valve very slowly when you hear gas flow...... Stop. then when you no longer hear open farther till full open.
The other thing is the ACME valve has a "missing hose" shut off as well.. On this ifthe coupler does not depress the pin.... No flow You night need new hose
Modern "You need to be protected" stuff is .. Well.. Safer.. But can be a Pain in the operation.
I used several different tanks with my Extend-a-stay.. No tribble at all.
