After you look over the dinghy list, you can then google the name, model and year of the vehicle, along with the words 'owners manual' most all modern vehicles have their owners manual online. Then find the section that addresses ‘four wheels down towing’ this might be under a heading like ‘Recreational Towing.’ If it says ‘Emergency Towing’ you’ve got the wrong section. There should be specific guidelines regarding towing procedures, necessary modifications, and safety issues. Other sections may address using a tow dolly as well. If you can not find the section that address recreational towing you will want to talk with a dealership or manufacturer, don't assume a sales person knows about this information.
