I would suggest a winch, but I watched “Truck night in America” the other night. An excavator arm would do just as well. I believe “shifting gears with aaron kaufman” actually modded a scout on like their first episode for off-roading. They seem to be kind of popular, I would at least throw a tarp over it to keep it from rusting away, if not an off frame repaint to knock the rust off it, that is mostly labor.
A dump box is almost priceless though. However, if you are doing loose hay, the a baler is also almost priceless too.
