A couple of things come to mind. First, you were at very slow speeds, the drivetrain is designed to take it, especially if you're under you weights. The only thing that might have caused problems were if you were in 4LO, as that restricts your turning ability. Second, you probably should have used 4LO on the way down to take advantage of engine braking. Again, if sharp turns are an issue, then you'd have to reconsider it. Just my $0.02...

Parts of the road were hard clay, which has excellent traction. There is no center differential on modern 4x4 trucks, meaning that there is no "slip" between the front and rear axle speeds when going around the corners.
With 5500 pounds on each of the front and rear axles with the trailer hooked up, what do you think is going to "give" when one axle wants to go faster than the other ? 4 wheel drive is to be used on poor traction surfaces only. Its especially not to be used on really good traction surfaces with a fully loaded truck.
FYI, my truck has a GVWR of 11,500 pounds.
