It depends. You can flat tow a Chevy Tahoe, but only if it has four-wheel drive and a two-speed transfer case. The two-wheel-drive Tahoe does not have flat-towing capabilities, so you’ll need to use a flatbed trailer to tow it. A two-wheel dolly is also not allowed, as it may cause significant damage to the vehicle.
To tell if you have a two-speed transfer case, look for 4-HI and 4-LO gears. If you have these, your ride has a two-speed transfer case and all-wheel drive, so you should be good to go.
