FWIW I've had two 2500HD cc/4x4/sb GM trucks, an 04.5 and a 2015.5 With both I tow a 32ft TT, 9K lbs and reese sway control. Never have I had any stability issues towing these trailers, including many trips up and down the columbia river gorge with wind gust to 50mph or so.

IIRC the extended cab has a shorter wheelbase than the CC, so that may impact stability. But a hitch not set up optimally can also have a dramatic effect on stability. And for a trailer as long as the OP mentioned, IMHO you need something that doesn't use the accy friction control for sway. Dual cam, equalizer propride/hensley.

Thanks for your input.
If I understand you correctly you feel I’ll be ok with my current Reese Strait Line WDH and the specs on the newer truck? I agree setup makes all the difference in a hitch, my current setup (done by the dealer) might even be wrong and I might get another option from another service center that’s local and only does service not sales. Might be worth my money to ask.
Thanks again

I don't have any experience with the reese straight line hitch. I tow with the reese dual cam.

However, I suspect that there is a good chance your hitch is not set up optimally. A quick way to check is to measure the height of the front fender arch unloaded and then loaded and hooked to the trailer with WD hitch hooked up. They should be the same. I'll bet when you measure you will find the front end is higher hooked up. that give some camber change on the front end and can make the front end want to wander more, feeling like sway. do NOT, repeat NOT adjust the hitch to have the front LOWER when hooked up. If you do,you will be riding on the bump stops on the front suspension and have a very stiff ride.

Don't worry about height of the rear of the truck, it will drop, you want to get the front back to unloaded height or as close as you can, certainly within 1/2".

there are some stickys (J Barca & Barney?) on hitch setup. Very good information from two folks who have great accurate knowledge of hitches and great ways to clearly outline how to set up and how to analyze your setup. Worth ready.

While you can have someone else knowledgeable set up your hitch, IMHO one of the best things you can do is learn to do it yourself. not that hard and then you will be able to adjust yours easily when the need arrises.
