All Wheel Drive
Anybody notice any major differences or concerns with 4x4 towing vs All Wheel Drive towing? Considering a Denali with AWD and the 6 liter.

OP did not ask about 2WD.
Almost every 4x4 made now turns the front axle all the time. Free wheeling hubs went out of fashion 20 years ago.
Ford superduty has 50% of the heavy duty pickup market. They all (4x4) come with manual/auto hubs, the front diff does not turn in 2wd unless the hubs are manually locked. So.... no!
Beyond that, just about every half ton (except Ram IIRC) has some variety of axle disconnect system. Manual disconnect hubs are out of fashion, but just the manual aspect.
I have a 2wd vehicle, and an AWD vehicle. I will start by saying that AWD systems vary so greatly, the OP's question relates to the specific system as much the configuration. For stability, and fuel efficiency, 4WD gets my vote, but it does have some understeer / tire scrubbing issues at times. For towing however, I would have some durability concerns with AWD.
The GM full sized truck AWD system is pretty good, (whereas the system in say the Chev Equinox is garbage). The engagement and slip characteristics on the half tons is stout, and should work well.
I'm not sure if that helps or muddy's the waters lol.
