Bought mine thru the dealer, cab is a Curtis, was a Massey option, red etc., cost was about $1500, I installed it, was a bit of pain in the butt!
Cab is fine does the job of keeping wind off while plowing snow in the wind.
Seems to be well made, I take off the doors in the summer.
Don't plan on taking it off when not needed as it would be another pain to remove and reinstall.
Work lites really install easily on the provided holes in the steel roof, all sorts of optional accesories offered by Curtis.
When installed really looks like the Popemobile!
