Looking for ideas/suggestions. I have a 2010 RZR. The radio is upfront, under the dash. I do NOT have doors on it. I was going to give it a go this winter and go from there. I do have the Polaris cab (front and rear glass and fiberglass roof with built in 55w halogen rear lights). I'd like something with off/low/high, a couple of vents blowing into the cab and some decent airflow on the windshield to keep it defrosted. During the summer months, I'd like to be able to prevent, as best as possible, from hot air still blowing into the cab. Thanks for your help.
