I had a full windshield on my rzr with no rear screen ...it was a dust bowl inside the cab. (I ride in Arizona) I switched to a half windshield and it seems to help quite a bit. Plus, it's much cooler with the breeze now blowing on me. Now, the biggest dust problem is keeping the dust out of the air cleaner box and the clutch housing.I have a pro r ultimate and running the front glass windshield. The dust is pretty bad in the cab, wondering if anyone with a 2 seat has put a rear window in with a front windshield and if it helps? I know the previous models a rear window helped.
