There are kits out there for this. I think the popular mod involves replacing the steering box with one from a power steering setup. Some use a box from a Toyota truck. They cut the steering column just above the box and put a secure union on to join it to the new box. All the truck suppkiers carry a new Pitman arm for this application.
I agree with the above comments in that having tires with good tread makes steering quite easy. When the truck is stopped, it takes a little more work. The steering in my 1 Ton is very light when driving down the road.
