For what I do, a cab is a necessity. Once I got a cab unit, never looked back (and stayed chaff free too).
I will agree that close in (as in woodlot) work could be an issue. Couple years ago I was doing some woodlot work for my neighbor and had the drivers door open and hooked the door on a branch and it 'exploded' literally. Cost me just shy of $1000.00 for a new door glass (used the original hardware and gaskets) and I carry a $1000.00 duductible on my farm policy, so I ate the door glass.
So yes, close in work with a cab unit can be touchy.
Live and learn. I keep the doors closed now.
