I did some work on an Eagle entertainer that had the generator radiator and fan in the tire compartment. It was so packed full of leave, mud, and crud that the fan had stalled.
Just curious, which way was the fan moving the air. Our fan is inside the compartment and pushes air throp0ugh the radiator into the area around the front axle. So far, we have never had any debris in the rad or radiator.
We did have to install a deflector on our basement AC discharge under the bus to prevent leaves & debris from being stirred up and pulled into the AC condenser air inlet. Jack
