I just had the pipe going to one of my grey tank break at the fitting. All I can figure is there wasn't room between the pipe and the chase it was run in. You can see where the fitting was rubbing on two side of the chase when the tank moved.
Took me two days and several hundred dollars to get it fixed temporarily, till my new tank comes in with new fittings. I sent pictures to Heartland and let them know of the problem. Hopefully they will review how they install piping in my model of Bighorn in the future. Hope you fix is easier than mine.
