Okay, found a .pdf of an old manual from 1991. Your gross trailer weight (tag) with 4.10s is 8500lbs with a 950lb tongue weight. Your gross trailer weight (5th wheel) with 3.42s, 3.73s or 4.10s is 7500lbs.

That's the link I took it from. Page 46. It's difficult to understand but it's there. That's the max rating based on 4.10s - you have to scale yours back for 3.73s, as it's only 7000lbs there.
