No Propane Flow to RV Appliances

I have a problem with the propane on my 5th wheel (2019 Montana High Country )

I just bought the unit second hand and have never used the propane system before. When I turn my bottles on, then go inside and try to light the stove, I get a short (1 second) hiss, and then no further pressure. If I let the system rest for half an hour and turn it on again, I get another 1 second hiss, then no more pressure. It appears that there is only a tiny bit of gas coming from the cylinder.

Things I've tried:

1) The cylinders do have propane in them, I estimate about half full.
How did you estimate? Propane tank gauges are seldom accurate. Did you weigh each tank? the side of the tank will tell you what the tank should weigh when full and/or empty. Personally, I would take the tanks and have them bleed out all the propane currently in the tank and then have them both refilled. I would also use a little piece of wire and run through all the propane tubes in your stove, then take a air hose and blow them out. Are the tanks beyond the certification date, if so buy 2 new tanks and have them filled. If this dosen't solve the problem, I would replace the propane the propane regulator.


Do you have any ideas of what I should try next? The RV is only 6 months old, so I can't imagine the regulator would be bad. I bought it from previous owners who had free electricity at their RV park, so the previous owners never used any part of the propane system.

Thank you!
