the main RV regulator was replaced with a Marshall 253H, which a Marshall engineer said was fine. Did a manometer check on the Marshall with stove burners and water heater running. It showed 11.5 at home (2500 feet elevation).
That's the same regulator I put in the camper 2 years ago. now the literature says it should be set for 11" WC from the factory not 11.5 so I wonder if they set them a little high on purpose. Which Manometer did you get?
When I bought mine to replace a failed one the spec, I was looking at was the BTU output as it was 350000 instead of 220000 so I figured having more volume would help prevent pressure drop better if you were running a bunch of stuff.
