Stop in for a cup of coffee

Had one on a tool truck. They get old and crispy after a few years. Then there's the snaps.:BangHead:
I need it on my plow truck, otherwise i get lots of snow in the engine bay. I really dont need one when the plow is on, travelling down highway i get negative air pressure and rad gets less air flow. So i either angle the blade or carry it only a few inches off the road.
