One real advantage of a cab tractor is that you don't really need to put it indoors. Sure, its nice to have it all spic and span in a garage, and the sun doesn't fade the paint so quickly, but having a cab on an outdoors tractor means you don't have the controls exposed to the elements and don't have to plop your butt down in a frozen puddle when you mount up...plus, you don't come in from snowblowing looking like a yeti.
