Was underneath the MH just doing some general maintenance and having a look-a-round. Saw a wiring loom that didn't look right so I did some further looking and found that it appeared to have gotten hot and melted the split-duct protection and I could see wire insulation showing. I had a sinking feeling that I was going to find copper showing. Cut back the cover back and dodged a big bullet as what ever happened only got the duct and no wires were damaged. Got it repaired and everything appeares fine.
This harness is about an inch in diameter so it has bunch of wires in it. There was a wire tie that has toothed socket to hold on a bolt that was also part melted. Also it wasn't on the bolt where it should have been. Far enough from the exhaust that Ford didn't feel the need to insulate it.
I wish I knew who to blame Fleetwood or Ford. I am leaning towards FW as it was right at the left front jack. I'm guessing when the bolts for the jack were tightened down the monkey with the impact wrench jammed it on the bolt and the rubbing socket melted the plastic. Lucky for me that the bolts were tight when they were and the damage wasn't rubbing on something long enough to cause problems.
Later on I was near the left rear jack and found some, if not all, the hydraulic lines rubbing on the frame, shock mount, crossmember and various other parts. Got started on fixing that mess.
Hard to believe what you can find if you just look. And only in 10,000 miles. QC, training and caring about your work, what a joke.
