We have had trouble with the furnace so I wanted to check the propane pressure to make sure the regulator was set correctly. An easy way to do this is make a gauge that will plug into the external quick connect propane port. Purchased a 0 to 30 inches of water gauge and a quick connect fitting from Amazon and mated the two together. Turns out our regulator was working properly. Thought others might be interested in checking the propane pressure on their coach.
