I carry a 20# propane tank in a tongue box and wish to run a reduced pressure flexible line via conduit beneath the trailer to the back near the galley. I was told that a high pressure line of that length (14') was a bad idea because of liquification of propane and line obstruction which is what happened with my first attempt. Last year on a 3 month road trip I lifted the tank out and carried it to the back of the trailer near the galley and that worked fine, but got very old--especially after I severely strained my back.
My plan is to put a primary pressure reducing regulator at the tank.
My question is what is the minimum incoming pressure for the existing regulator to function properly for the 2 burner counter top stove?
That seems to be the primary concern of the propane professional who is now on task for this project.
