Tow Pro: what tow vehicle to buy?

I'm in the process of looking for a new Dual cab ute for work but also to tow my new Jayco Sterling Carvan (21.65 3) which we pick up next year. The van way's 2.1T empty so would asume by the time you load up with water, food and clothing the van would be getting close to 2.4T. Iv'e been looking on the net to try and help me decide which ute to get but the more I read the more confused I get. Iv'e owned three Rodeo's and been happy with all of them my currant one is a tray top 4x4 diesel, can you give me any advice as to which one you think would be sutible for the job.
