Strange Ticking inside the wall
My coach is a Tiffin Open Road 30GA
Had a strange thing happen this weekend while filling my MH with gas. Pulled into the gas station that has level concrete pads. When I stopped and turned off the engine there was a loud ticking coming from the upper cabinets on the passengers side just in front of the refrigerator.
At first I thought something was rolling back and forth in the cabinet so I opened several and looked inside, nothing there. After about a minute of looking the ticking was still going on in a regular rhythm, about once every second. I thought it must be something hitting the outside of the coach. I got out and looked, saw nothing. I thought maybe it was water dripping from the gas station canopy. But no, there was nothing dripping from above. I could not hear it from outside the coach, only inside. It was something very mechanical sounding.
I filled up with fuel, 28 gallons, got my receipt and went back into the coach. The ticking was still going on at the same rate. I started the motor and pulled forward several feet and the ticking stopped.
I have never had this happen before and as far as I know there is nothing mechanical behind the cabinet wall or in the ceiling at this location. It was about a foot from the refrigerator toward the front of the coach.
I only went into town to get fuel and propane for an up coming trip in several weeks. But the coach has been parked so nothing was or had been turned on or running for several weeks. It is stored inside my barn and plugged into a 120v circuit to run a dehumidifier.
I got home, put the coach in the barn, leveled it and turned it off. All was quite, no ticking, no other sounds except the engine cooling down.
I have owned this coach since August of last year and the wife and I have traveled to Texas, Tennessee, South Carolina and all the states between and I never heard this noise before.
Any ideas or help explaining this would be appreciated.
I know the voices in my head are not real, but man do they ever come up with some great ideas!
