Steer tires

No sway when NOT towing.

Would moving weight back not be more advantageous by taking weight off the steering tires.

Brand new tires with the new rubber compounds can create an instability. After 1,000 to 2,000 miles this often goes away. I am on my 3rd set of Continental Contrac TR's , new this July and they did create a shift in truck stability even on heavy LT tires. However this effect goes away once broke in. I did not have this issue on the last set, 6 years ago, only this set. Same tire, same truck and camper, just it reared it ugly head this time.

If you are having instability issues on the front of your Tahoe, and you are not on brand new tires, I would first suspect tire sidewall flex not so much the tread pattern. Soft side walls are a classic for creating towing instability. Airing up the tire to max sidewall pressure cold might shift it to being better as they are then stiffer. If the truck literally bounces left or right when you hit a bump when towing, then air down 5 psi from max and try again. Do not go below door sticker pressures. You can air down the tires again to normal when not towing. A pain yes, but it is cheaper then new tires if it helps the problem. Air pressure in the rear tires is also part of this as well for the same problem.

Taking weight off the front of the truck axle needs a lot more info about your camper, hitch and trailer if that will help any. Normally that is not a problem as long as the tire itself is up to the task and not overloaded. The weight distribution on the truck from your WD hitch has to be correct. If that is not correct then the whole truck can start bobbing up and down creating issues.

Hope this helps

PS. Are you having stability issues? and if so what lead you to think it was the tread pattern? We need more info to help the underlying issue.
