The number one reason for all the dust inside your Rhino is because their exhaust is pointed downward, which kicks up all kinds of dust that is then sucked inside the cab. Having a windshield and a back cab enclosure only worsens the problem by causing a vortex inside the cab. I tried three different windshield (full, half, vented) and there wasn't a whole lot of difference when it came to the amount of dust sucked into the cab. Having the air intake inside the cab doesn't help matters either.
I had a muffler shop mod the exhaust on my 07 660 so it went straight out (cost about $50.00) and it dramatically reduced the amount dust both inside the cab and in the air for others following behind. Far better than any gimmicky windshield with vents, etc.
