I expect mine will become a plow truck when it retires from daily driving duty.
Many vehicle's suffer from brake and front end premature wear from the extra weight placed on the vehicle.
All that said, if /when it gets to a point where it is no longer practical for street use, a plow may find its way onto the front end.
I had pretty much ruled out combo street/plowing use however, with beefed up springs to handle the extra 500 lbs from the plow and harness, You may get away with it although I am sure Toyota would not approve.
