Which Yeti

Find a replacement for my Jeep Grand Cherokee, as I no longer need the large trailer load (3500 kg) for my boat. I thought about a Yeti, driving about 10-15000 KM a year in the city-land traffic. From time to time I have my two-axle trailer to pull, however, because the 2000 Kg trailer load. (mostly) It should be an automatic circuit. What motorization would be the right one?
