A leaking wheel cylinder can ruin expensive brake shoes.
I watched my dad try 3 times to put a wheel cylinder kit in one wheel. It would work for a few days then start leaking. He even borrowed 3 different brake hones from a shop. He finally gave up and bought a new cylinder. More than likely his wheel cylinder was past rebuilding or he didn't have the skills to lap the cylinder correctly. Sometimes the cheapest route is to buy a new/rebuilt cylinder and be done with it.
Consider Mike B's recommendation. Like anything, there are pros and cons. DOT 3 is hygroscopic (had to check spelling on this one). It absorbs moisture. Moisture in a stock cylinder causes rust. Maybe someone in Las Vegas can give you the odds on when you would need to rebuild again, I can't. I don't own a 2 ton but I can imagine taking the wheel and drum off the big truck is something I would have to struggle with.
Does your truck have a Hydrovac? You probably know the info in the following link but it has some good pointers on bleeding the system.
