I'm struggling with the same thing. All options out there it seems require the purchase/installation of a hitch. I haven't been able to locate a universal type trunk mount which would be most ideal. Hoping someone out there has solved this problem!
Unfortunately, when you go to the THULE website and you provide your vehichle (Hyundai Palisade) it says that no bike racks fit for the vehicle. The one bike option under Saris won't work unfortunately. Thank you for the suggestion however!
