Not sure. I tried looking to see how wide they are, but can't seem to really find anyone that actually knows, even the toyota forums seem to be unsure about it. The first result I found that could've been useful was a post on pirate, which of course after three replies degenerated into their typical name-calling argument which made the whole thread pretty much useless. But it sounds like they are supposedly the same width as the T100's, which is 66.75" or so. I have no idea how wide our axles are. My boss actually has a newer Tundra I could measure the axle on, though I'm not sure where exactly to measure it to.

Our stock rear axle is 68" from WMS (wheel mounting surface) to WMS...basically rotor to rotor.
Depending on the year they are 5 or 6 lug. The new ones are 5 lug but a 10in ring gear. They currently are limited in gear ratios but aftermarket will catch up. If they are non full float (which I imagine) abs sensor work will be more difficult. Full float housings are the easiest to get abs to work and that's how I did my eaton HO72 rear axle.
Non full float housings will require other methods.
If the rear axle is within an inch or two I say call it good.

What would make the Tundra rear end an upgrade over the H3?

The H3 rear axle is very good and I have nothing bad to say about it. 10 bolts have a TERRIBLE reputation but in all honesty I never broke a R&P even with severe abuse on 37s. I broke a stock shaft after 8 years worth of trails and on sledgehammer in JV on the plaque which is a trail that 90% of wheelers can't even get to or want to get to. I could of had chromoly shafts made but upgraded to a new axle. If it was me if you wheel muddy terrain run 37s and a locker and your fine. If you wheel hardcore rocks on 37s get chromo shafts. If you wanna play really hard and think you might go to 40s one day upgrade the axle.
Overall the 10 bolt is a damn good axle

Not sure I consider a Toyota axle an "upgrade". Maybe more like a "side-grade".
Of all the things GM failed so miserably at, when designing the H3....the 8.6" 10-bolt rear axle is a shining example of the perfect component for the application. I honestly can't think of any other axle that would be better for this vehicle, at this weight, for this type of use.
