Hi all - possibly looking to get back into a Volvo. My wife and I really likes the XC60. Since we are going back to an SUV, we decided it would be nice to be able to use it to tow our boat, but the tow rating is fairly low at 3500 lbs. However, GrecianVolvo says it's 5,000 lbs, despite screen shots of the owner's manual saying it's 3500. What's the definitive word on the tow rating? Thanks!
