Snowy, that tow weight is within the limits of the 2 door which is 1600 kg but it is over the tow ball weight for both the 4 dr (170 kg) and the 2 dr (160 kg).
If you can move some weight back in the camper to unload the tow ball, there is no reason why you couldn't get away with a 2 dr.
With that much of a tongue load I'd want to help the rear end out with some polyairs.
