Any idea where the US payload will finalize, the US brochure says 1841 lbs with no driver, the Australian brochure says petrol 5 seater at 1999 lbs. The guys at the demo say they have like 5 different spring rates and said 1600lbs. Just curious if anyone has anymore info on this for the US spec? Also anymore rumors of a longer wagon with true 2200 lbs payload?
