Towing 26' with a 2003 Yukon SLT 5.3L?

2003, so a GMT800 and recommend changed it (if the previous hadn't
already) to a traditional receiver. They are in the $200 buck range, plus
about 1 hour to install

Can you clarify what you mean here? Have they recalled the trailer hitch receiver?

'Swaybar', as WD Hitch component, or rear axle anti-lean bar?

I do not recommend adding a rear axle anti-lean bar...unless you also
increase the stock front anti-lean bar to keep the handling the same.

The OEM dialed in the understeer/oversteer characteristics and changing
the rear can have an oversteering TV that will have a greater jack knife
tendency...not a good thing

I'm not familiar with a rear-axle anti-lean bar. I meant a friction-based sway bar mounted to the WDH, unless I end up getting a WDH with an integrated sway control like the Equal-i-zer.

I had a 1973 K5 Blazer (2 door Blazer/Yukon) and installed 1 ton
suspension (Dana 60 front and GM 14 bolt rear...new leaf springs front
and rear) and towed many trailers

It also had commercial class tires with a load range G sidewalls.

Not fun and was all over the place when passing semi's and even passing
a stationary TREE on the side of the road.

But that had 106" wheelbase and was rated for 5000lbs towing and a 450 tongue weight. You clearly know more about trucks than I do, but it sounds like quite a different TV.
