Questions about tire and axle loading

I've got a Ford F250 3/4 Ton 2014 SRW SuperDuty SuperCab XLT 4x2 6.75" Short Bed Gas Engine truck.

The first question is about the tires which I think I know the answer to: I have Load Range E tires with a max load of 3195#. My GVWR is 10,000#. Focusing on the rear tires, my rear GAWR is 6200#, so is it correct to say that the weaker link is the axle (at 6200#) because the two rear tires can support 3195*2 = 6390#?

The second question is that I went to get the truck weighed at a scale and the rear axle load (without camper) is 2820#. I believe this means I can put up to 6200-2820 = 3380# on the rear axle right?

If so, does all of the weight of a truck camper go on the rear axle? If so, then that would mean that my camper wet weight can't go over 3380# right?

I know the GAWR can't be increased, but do things like a rear stabilizer bar do anything for safety or is that just for ride comfort?
