Duane, I agree that if the Hayden 2797 worked for me as it does for you, it
would be my first choice. The 2797 NEVER stopped "roaring", and the 2747
"roared" continuously until I reached 45 MPH. This happened with an empty
coach. It also happened with a 20' boat in tow, so I think my cooling
system is OK.
All I want is the same fan clutch as my original. It hardly ever came on.
