A lot of people say that's amongst the softest sand in Aus Cj, so good example.
Last weekend we had a great mix of 4x4s in the same area. 1 Triton, 1 brand new Hilux, 2 x 2017 4.5l tdv8 LC 70series one dual cab one single on 15inch wheels 100series, and our D4.
Only the 100series and D4 made it up Calcup first time "as seen in later part of my youtube vid posted.
Big mud hole we had to go through had the dual cab 70series stuck, got pulled out, D4 got out after it grabbed traction after about 5sec wheel spin and then straight up. 
Dual Cab 70 series weighs 3.6t as is, ours weighed 3.56t when loaded for gib, most likely 3.4t for this trip... 
Has to be like for like comparison weight wise. Wouldn't expect to keep up with a stock standard 200 series when I've got an extra 300kg in accessories.
Might surprise some people that a kitted out D4 weighs as much as a dual cab 70series...
