Happy vacationing! Yes, you can flat tow a 2021 GMC Yukon Denali provided that your vehicle is equipped with four-wheel drive. You’ll still need a little bit of extra equipment in order to attach one vehicle to another, but you won’t need a tow dolly or a trailer.
If your GMC Yukon Denali is not equipped with four-wheel drive, however, you’ll need to use either a trailer or a dolly in order to tow your vehicle. You don’t need to purchase either of these—they can be rented from most moving truck rental companies for the duration of your trip.
