i had mine in front of the rad before. now ill have an a/c condensor there. not sure if theres room for all three and anyhow i dont want to get too much stuff stacked up under there to inhibit airflow. its got an therm controlled pusher fan on it. i was thinking about mounting it to the backside of the expanded metal part of the grill guard but think this would look ghetto. anyone have any experience mounting something like this in an area thats not in direct airflow. maybe somewhere well protected under the truck?
