They were used on 1 tons a lot more than they are today. However I have never sean a wing on a pick up. The wings are out there, only they won't perform like the ones the DOT has.
To have a wing that works like the DOT's ya need a truck like the DOT's. Be ready to drop 9K for the plow and wing, with out a mounting frame.
There only real use is in road plowing, they won't help plowing lots, only get in the way.
