My wife and I have a 31 foot 5TH. wheel that we pull with our 2003 Ford it has about 89,000 miles. On our last two trips we noticed it makes a heavy breathing sound. It is more noticeable in the summer than winter. My brother in law said his diesel was doing the same thing; and we were wondering if it had anything to do with the turbo motor drawing in more air.
