I have just purchased a 2007 2.2l diesel Santa Fe and tow a jayco Freedom 15 foot caravan weightin 1350 kg loaded. I am confused. Have spoken with two reps from the same Hyundai dealer and have got two different opinions about towing using 4th and 5th gear. Common sense would tell me that I need to use 4th gear when travelling in hilly or mountainous terrain or heading into winds etc. But on flat going the vehicle seems to tow in 5th gear with ease. Am wondering if there are other Santa Fe users who might like to share their caravan towing experiences with me specifically what gears they prefer to tow in and at what revs and fuel usage.
