My guess is the latter as well. I looked at FMCA's 2017 towing guide (http://prodcontent.s3.amazonaws.com/motorhomemagazine.com/2017DinghyGuide.pdf) and it doesn't list any KIA vehicles as being towable 4 down. If it's AWD, a tow dolly wouldn't help either. I followed the link to the Remco site that John posted and, although it doesn't show a link for 2018 Sportages, it indicates that 2017 Sportages in AWD form must be trailered.
