Replacing 80 series Turbo Diesel with either Prado o Nissan 3.0l Turbo Diesel

I am considering replacing my 1992 80 Series Landcruiser Turbo Diesel, used mainly for towing a 2,000Kg caravan, and notice that both the Prodo and Nissan 3.0 Litre turbo diesels have roughly the same power and torque as my cruikser, and both have respectable size fuel capacities. Can I expect the towing capabilities of the Prado and Nissan to be similar to my Cruiser.

Any input from owners of either Prado or Nissan Turbo diesels would be most gratefully appreciated.
