I keep destroying my secondary regulator. Help

I have a 2014 Wildcat with a 30 lb tank on each side of the unit. The main two stage regulator is on the curb side with a small 30 psi on the street side. I have replaced this regulator three times and the fourth unit failed this weekend. What is the problem with this regulator set up. What am I doing wrong? I turn both tanks on when we get ready to use the unit so I don't think I am triggering a safety shut off. I have tried using the street side and the selected tank as well as the curb side. Doesn't seem to matter, after a few months the regulator quits flowing. Is there a way I can safely get rid of this regulator? I appreciate your input on this problem.

Thanks
jim

    It's most likely this. I had both tank pigtails go bad after two years on a new rig. The tank pigtails have a high flow shut off feature in the event of a catastrophic failure and they can malfunction. I would replace these.

    I haven't checked this regulator yet. I am sure the previous three were regulator failures. I don't remember brand, I have had two red and on gray, the one on it now is red. I have tried tapping on the regulators in the past, I have tried switching bottles. When I change one out it will work for a little while but not very long. This one was installed last fall. It was tested by an rv tech and showed very little pressure.

    The high pressure regulator is required by code because the connecting hose exceeds 60".

    What exactly is the failure? Have you tried a different brand? I like the Cavagna regulators and pigtails.

    are you sure its the regular and not the valve being opened to fast after you get the bottles filled?
