That makes sense. I can see where it would frost up in cold weather with an enclosed cab.
I don't want a fully enclosed cab. With the windshield though, I figured a rear panel would be needed so dust doesn't roll in from behind in dry conditions. Then a top for shade/rain/hail, etc. I chose a two-piece windscreen, so it can open up and let air flow in when it's hot.
A full windshield really sucks in the dust. We have one that opens. Running open reduces the dust by 75% or more. It just blows through.
