They do have traction control but in my experience traction control is more of a hindrance than a help in the snow or ice.
Hindrance? When I first got my SD, I couldnt figure out how to shut it off. with barely a dusting on the road, up a SLIGHT incline...I was spinning. Whenever I use 4x4, it has to come off if I want to be able to go anywhere.

same here - keep it shut off all the time. If it’s on, and you need to get through a small windrow of snow left by the town plow when you’re turning onto a side road, if you give it a little gas to punch through, the truck thinks you’re going to die and kills the throttle. Annoying to say the least.
As I outlined above I have had only two 4WD vehicles, the F150 had both axles limited slip in '95 with only the rear on the F350 in '04, I guess I never had the opportunity to find out if open front and rear would work well...I do use snow tires in winter so I have that working for me...so these trucks do not have anything in play that uses wheel spin and ABS to control the traction or slippage ?
Yes they do. When you are in 2WD, you have rear-wheel traction control. When one side slips, the ABS sensors detect the speed difference and apply a pulsing brake to the spinning side...this forces power across to the other side which does have traction. When you engage 4x4, traction control activates on the front wheels as well. The traction control system does include both throttle and brake control. So the brake pulsing to transfer traction is very helpful, but the throttle reduction is usually not. Sometimes you just need momentum to carry you through a stretch, and in this case when the traction control engages, the throttle is usually cut to a very low level. When you know you need momentum (deep snow, mud, etc) it is wise to disengage it. But for getting unstuck or low speed maneuvers, leaving it engaged is very useful.
These trucks go extremely well in snow, so long as 4x4 is engaged. They have a more severe front weight bias than a half-ton. An F-150 is able to drive through snow in 2WD that a Super Duty must have 4x4 in use to move, even with snow tires.
troverman, what is being disengaged? Does it matter that I will have a manual transfer case and manual locking hubs? and from the sound of it what you are referring-to has nothing to do with the Electronic Locking Rear End, correct...

Gotcha, thanks. What I mean is to disengage the electronic traction control. There is a button on the dashboard that allows you to disengage it. One press disengages, a long press disengages stability control. This has nothing to do with manual or auto 4x4, locking or open rear ends. All trucks have this button.
Thanks, troverman, I will watch for that! am I wanting to do the short press or the long press to disengage both traction control and stability control ?

The truth is you can never *fully* disengage stability control, but short press shuts off traction control - throttle intervention; long press shuts down stability control - brake intervention. Sometimes the short press helps. Fully turning it off by a long press also means the anti-skid portion of stability control is reduced. Low range will notify you via the message center that stability control is off.
For winter driving once you are above 20 mph, there aren't many situations an open front and rear diff won't get you through.
Granted, Im from Alabama, so my experience with snow is limited, but in my bit of snow driving, a locked diff in the rear is worse than an open diff. I would expect to use the locker like someone else said to perhaps get moving when one rear wheel is spinning on ice and the other has traction, but I would definitely NOT recommend driving around with the elocker engaged on snow, it will cause your rear end to try to get ahead of you!

Uhm, no. Not no, but hell no as a matter of fact. I have had several offroad rigs with Detroit lockers, you do NOT want one of those on the road, period. They will shove you this way and that in a straight line, and they will unlock in a turn and sound like a gunshot.
I am actually in the process of building an elocker to replace my current grizzly locker (a Detroit copycat) for my trail rig. The elocker is lightyears better. I have never met anyone who, having had both, prefers the detroit or trutrac over an elocker in the rear, and I do a lot of serious 4X4ing. Front axle is a different story, the elocker can be a challenge.
I have auto lockers in the rear of all three of my vehicles, they are hardly noticeable on the street, they don't push the truck around at all. A locked rear with an open front does great in the snow also. For the rear I much prefer an auto locker over a selectable.
