FYi, propane tanks are filled to 80% capacity only by law. This allows for expansion in the heat.

If you have a leak, you could have triggered the safety valve built into the tank valve. If it detects too fast of a flow too quickly, it closes to prevent leaks... to demonstrate, turn your valves on a BBQ, then open the tank.. you won't get any propane flow, and you'll hear the click from the valve as it closes.

I think triggering that valve is what did it Morpheus. I've ordered new pigtail hoses and another regulator. I'll install everything but keep the old regulator as a spare because I don't think at this point, it was the problem. Since I'll have it apart, I'm going to replace the regulator so I don't have to worry about it for many years to come, fingers crossed.

I had that problem with our Weber Q200 grill. I have to turn the gas tank valve on then wait a while for the pressure to equalize in the hose to the regulator before lighting. Otherwise, the grill may light then fizzle out in a few seconds. There may also be another check valve in the regulator to complicate matters. There were people blasting Weber in product reviews because of this. Weber has a statement on their website that addresses the problem and explains what to do. Mainly, turn the the tank valve on then wait a few minutes before lighting.

Having said that, the same practice of turning the trailer tank valves on and waiting a few minutes before lighting any appliances may be a good practice to follow.

I have the new marshall auto changeover regulator and new marshall pigtail hoses installed and so far, so good. The system charged and lit like normal. I haven't been out camping in the trailer yet but I hope to soon.
