Is anyone currently using either a Nissan Xtrail 2.5 lt petrol with a CVT transmission, or the Renault Koleos 2.5lt petrol with a CVT transmission as a tow vehicle. The Xtrail and the Renault use the same engine transmission etc. I am looking at replacing my tow vehicle and would like to hear from anyone using either of these. My concrens are around the issue of not using a WDH (Nissan recommend you do not use one) and the vairied towball down load weights (dependent on the load you place in the vehicle. thanks
