I find that table really hard to interpret.

So I built this comprehensive spreadsheet that allows you to track and monitor all your trailer towing weights, and measure those against the maximum specifications for your model. The spreadsheet assumes you have 3 sets of (CAT scale) measured weights: the base vehicle weight, the TV plus Trailer weight (without WD), and the TV plus Trailer weight (with WD). That spreadsheet is attached at the bottom if anybody wants to use (or improve upon) it.
Does it make a difference to any of the calculations if your trailer has two axles? Or does it depend on the wheelbase distance between the two axles?

PS: I have updated the spreadsheet in the original post, please re-download if you're using it. This newer version is more of a template allowing the user to plug in their own values.

I agree, it's not clear, but for the rear axle section there are 3 columns. One for the 8.8", one for the 9.75" and one for the raptor 9.75". If the values in the rows are separated by tabs or spaces, then they apply to that particular axle. If there is no spacing between the values in the rows, it applies to all of them.
So, any of the axles can be one of these types; standard/limited slip/e-locker. The 8.8 has a rating of 3800 lb. The 9.75 can be either 4100 or 4800 lb rating. For the raptor, it can be either 3500 or 3700.
The mystery still remains... what is special about the HD 4800 axle aside from one extra lug.

I've tried searching some of these answers for years..it gets too complicated sometimes. My grandads old 4.6 2006 long bed 4x4 has the 8.8 which was rated the same rgawr as my 2011 9.75. I never one bought that the ratings would be close, try comparing the two diffs and there is a huge difference. Most of the weaknesses are in the spring/tire/wheel package..
