We have a great place in Idaho Falls that does custom tops (boat covers etc.) . wipers are manual, not too tough to just do a quick wipe if it is snowing hard, electric motors kinda weak that I found. I enclosed ours all the way to the back , motor heat keeps it comfy inside , use a small squeegee to keep inside clear.Very nice, wife and i are thinking of these for ours, we live in Northern Maine and can use on trails if we register as a snowmobile. where did you get your cab enclosure? and is your windshield wiper manual or powered?
