I'll preface this by saying I don't plow snow. However I do use the full hard cab for hunting. About all it will do is keep some of the elements and some of the wind off you. I've tried to seal all the air leaks and find that impossible to do. The doors will greatly decrease your side to side visibility. For extended plowing or during sub zero days, you would most likely need some type of a heater.
The hard windshield with wiper, hard rear window, hard roof and the doors are not that difficult to install. They are heavy to say the least. You will probably need the help of a 30 yr old person. (I'm 73)
Owning the complete hard cab at a cost of almost $3000. just isn't worth it in my opinion. With that said, I've seen some great after market cab enclosures that are much better and cost a lot less. Sorry, I can't recall the brand it was. I do remember that the complete door was see-thru.
Lots of good folks here, someone will have first hand experience at plowing.
