Thanks for the update. I had one go bad on my new trailer. It was obvious though (loud spray from a hole in the regulator). Thankfully it did it in the driveway at home when I opened the tank and not on the road. They were cheap, so I ordered 2. I assumed the one on the other tank would probably go too. Three years in and so far so good, but I have the other one, in case.turns out my regulator was bad.
