Tom,
I added the cab a few years ago, outstanding. Of course I live in the north and use it to plow. Built my own heater from a heater core and a metal surround and small fan, very comfy in the cab. Glass windshield with wipers, again perfect combination. My favorite mod is the hand throttle kit. Should have been factory option, imo.
Is this the steel cab you are considering. I installed this one a few years back. The only air leakage in my case is around the bottom of the doors, but I have found that sealing it up too tight results in condensation on the glass windshield. Two heaters running off the RTV cooling system ...one vents through the cup holder driver side and the other in series with the first blows warmed air at the drivers feet. Door are easily removed for summer use.
Of course a new 1100 would be so much more comfy but I like the smell of the money I won't be spending on a factory equipped machine.
Water tight yes, short of going into 12"++ of water. As far as air leaks I had to add seal around the hood, and block off the 14" wide by 16" tall area where your horn is mounted. I can try to take pictures. In a perfect world If I had the option to buy a new model that would be the way to go for sure,factory cabs are much better insulated plus all the other bells and whistles you get. For what I use my 05 900 for, plowing and towing my boat to the launch down the road, firewood and any other excuse I can find it suits me well. Althogh i have always liked the looks of the 1100 better. Somday....
