As long as you have a hitch that will handle the weight, the only concern would be braking. Often times a dolly will have a hydraulic brake built into it that applies when weight is distribution moves forward on the dolly.
Is that what they are worried about? Also, in your owner's manual, it will identify the max towing capacity. Certainly, anything over 1000 points should have some form of braking device but your vehicle will pull it.
Please confirm if the Tahoe's engine is a 5.7L or a 6.5L diesel.
Take care and let me know if you have other questions.
