I'm contemplating on adding one for my 2500HD 8.1(2003 CC short bed) stock height Currently 265/75/16 but will upgrade to 285/75/16

Any cons in having it?

75% none to light tow

25% 9k+ weight plus trailer
 
I always thought a rear sway bar was to help with controlling loads. Since you hardly tow, maybe upgrading the front sway bar where all the weight is might be a better option for you. No real cons to upgrading the rear sway bar if it's a street driven vehicle. I could be wrong about this, but I'm sure someone will be along in a few minutes to correct me if that's the case.
 
Sway bar helped my excursion, but I'd say they are a higher COG. But my timbrens helped the most.


Do you feel you are getting body sway OP?
 
I put one on my last truck(Ram 1500) and it was huge. I miss it on my Tundra and am planning to add one. It was noticeable just unloaded but with a trailer on the back it really helped.
 
You could try changing out your OEM sway bar bushings for poly bushings. I did that and noticed a difference. I installed KYB shocks and struts when my OEM's got worn and that made a huge difference.
 
What shocks are you running?

I added Bilsteins 5100 on my '15 Ram along with 5k Air Lift bags and it has helped when pulling my heavy bumper pull toy hauler. The rear coils on the newer Rams are kinda wallowy while towing heavy and the air bags and shocks firmed it up.

I haven't check if there's bigger front sway bar, I know it would helped, just saw local ad for rear sway bar

Airbags for when you're loaded.
I'd like to get that someday

Body sway feel more than my friend's stock 01 Duramax in same body minus 4wd

That's what I figured, I'm used to having mini truck and sporty car having them, not sure if worth/noticeable on HD/towing which seems like it does

That's a good idea, I'll see if there's any for the sway bar poly bushing available.

I put a hellwig on my 2005 Dodge 2500 that had a massive cabover camper on it, it did really help.
I figured it would help, good to hear feedback.

Bilstein 4600 in front(5100 was on backorder) and 5100 on rear. It helped out a lot but still more than I expected especially in mountain/canyon on sharp corners

I tend to drive more slower when towing so that doesn't
