Many trucks have proportioning valves that sense the load in the rear and apply more brake pressure to the rear to take advantage of the weight being back there.
And you ain't gonna transfer no 10,000 lbs of weight to the front axle unless you stand the truck up on its nose.
I saw no where if the OP has discs or drums in the rear.
I know on my 97 3500, you could use chevy 1 ton wheel cylinders in the dodge drum setups, and it worked tons better, especially when loaded. I think they were a larger diameter wheel cylinder.
