Yeah, I was a bit surprised. My trailer is stored indoors all winter, but it isn't heated. I leave the LP connected (bottles turned off) during storage. I suspect the plastic failed from the extreme cold we suffered this winter.
I find those short hoses tend to be quite inflexible and I always turn my tanks a bit to take the most pressure off of the connection. This winter didn't help much for most units stored outdoors with the extreme cold.

Wow...that just happened to me that I posted in another thread. I thought I would check propane before we leave out. Gas was off. Actually on, but one tank was empty. Connector on full tank was broke so automatically shut of full tank. Dealer gave me a new one and I replaced myself. They sell them everywhere.
I picked up a new hose assembly and installed it. The dealer said these break all the time. He said it is usually from kids stepping on them or the side stress of a tight hose on a cylinder positioned poorly.
