2 or 3 hours with a truck? That must be one long driveway and no place to put the snow after a while. A blower on a tractor will be a dream. I'd skip the cab and not even build one. Just get dual remotes to control the chute and the deflector. If you can blow into the woods you have two sides to choose from depending on the wind direction. Go for the HP. Also, shop around for the best blower - large diameter second stage, 4 or 5 paddles, long chute so it will keep up and you can blow at a good speed. If you have to build something, some bolt a sheet of Plexiglas to their ROPS.
