The JKU has a lighter duty frame, lighter duty suspension, lighter duty transmission/transfer case, and lighter duty brakes. The axels are defiantly capable of more weight because if you look at GVWR the Defender and LC 70's are much heavier vehicles as well. Those two are built more like a full-size truck here in north america which are capable of similar payloads. It seems to be a lot of all those things that when combined together make a difference in the rating. It could be an impact to the differences in safety standards between trucks and SUV's. It could be Jeep not wanting to rate it higher so that almost anybody modifying, loading and using it can never sue them because they can always come back with the "well you were operating it above the GVWR, an operating condition not certified, studied, or authorised..."
I never understood how Jeep couldn't rate the Rubicon version here in the States with a higher payload capacity. But again the main things upgraded are the axles, suspension (and maybe brakes?). Leaving the other parts as the limiting step maybe. So in North America a Rubicon version will come with a lower payload capacity than a non Rubicon version due to the added weight of the modifications... I know confusing but again not everything related to payload capacity was upgraded...
I am not sure where you are located but if the safety thing is a big concern for you I think you will be pleasantly surprised by the safety, payload, and capability of the Toyota 4 Runner for overland travel. If I remember right it is about 680kg payload. Gets better fuel economy than any of those listed above allowing you to drive the same distance with less fuel weight (another plus to perceived payload capacity). Easily upgrades front and rear bumpers and locking differentials. Remember the payload spec on the JKU is for the base. Add on the hard top (vs soft top) and things go down. Now if you strip it down you could easily take off 100kg (lighter seats, no rear seats, soft top, full soft doors, etc. and your payload goes up allowing you to add on some critical stuff and keep payload good (remember larger tires kill payload very very fast).
I have to admit if it came down to me needing to buy a new vehicle in north america it would be between the JKU and 4 Runner with the 4 Runner probably winning. If I had the choice of any vehicle made it would be a Defender 110 HC or Landcruiser HDJ79.
Howdy I come from Sweden, Europe and have a unlimited Rubicon with payload of 545kg with hardtopp.
"The JKU has a lighter duty frame, lighter duty suspension, lighter duty transmission/transfer case, and lighter duty brakes" I do think so to but I have no facts for it or link or test or pictures, but if looked at payload do they have three times as big and sturdy stuff of the above things, I dont really think so.I do think that they have higher payload because there are trucks and Wrangler is a SUV, and therefore have different payload ratings besides that the are sturdier. But do some one have real facts, links etc that a Defender have more heavy duty brakes compared to a Wrangler. I know that US wranglers (11.8" rotors) have small brakes compared to the Australians and probably all export wranglers that have 13.25" rotors and bigger callipers. "07 to 09 have the same brakes as the US guys, export models upgraded for the 2010 model to the 332mm 13.25" front discs" from http://www.ausjeepoffroad.com/forum/showthread.php?t=124592&page=2
I think wrangler export models have similar brakes like TeraFlex Front Big Brake Kit http://www.quadratec.com/products/12700_4200_07.htm
That could be one of the reason that US rubicon unlimited has a payload of 405kg, compared to my European spec rubicon unlimited that has a payload of 545kg with hardtop. Can you fit a even bigger brakes to a export Wrangler? will they fit? I wonder? Is it then possible that a Defender can fit bigger brakes on there wheels that are about the same as the Wrangler, I doubt that and here they say that Defender have lousy brakes https://translate.google.se/transla...rbel-bei-den-haendlern-731019.html&edit-text=

The 70 series trooper is probably like a US full size truck but probably not the other smaller 70 series and the Defender is actually shorter than a Wrangler and less wide and have shorter wheelbase. I do think You are right that I also wrote before that the rating is probably different on SUV compared to trucks. As I wrote before that Toyota landcruiser 150 (prado?), payload 570kg, Jeep Wrangler unlimited, payload 545kg, Landrover Discovery LR4, payload 650kg are probably in SUV payload rating and there for lower? I think Jeep for safety sake have low payload to avoid problems in tests like this Grand cheroke that failed the famous moose test, se the movies
But Jeep listened and 2014 is great

Toyota 4runner looks great but what I can se it is not for sale in Europe or in Australia http://www.toyota.com.au/home or in South Africa http://www.toyota.co.za/. Is 4runner only for America?
And the Toyota Fj cruiser aint for sale in Europe
