That was very clear.
Many popup trailers have in/out stoves that hang on the side and hook to the quick disconnect. Atwood stoves that are mounted in a box with hanging rail.
Scroll way down to see how this guy hooks up both his weber Q and low pressure stove via the quick disconnect.

Low pressure stoves operates on regulated low pressure while a high pressure stove like Coleman operates on regulated high pressure, both connect to container pressure, regulated differently. Confusing container pressure for regulated high pressure is common.
