Ours is the Triton 430 bought here in Germany. I have no idea what diamond pack includes but ours came with what is called a 'Touring Packet' which included:
Alloy wheels 185/70 R14, Spare wheel (steel), Fly screen on door and all windows, Wooden cutting board on sink, 30L cold water tank and 2 x extra 230V sockets making 4 in total. Oh, and a 80x50cm access hatch to the stow room under the bed plus the 1200kg axle.
With no gas bottles on board I took the Triton to our local weighbridge and it came in at 909kg.
