OK, I've noticed this several times and I chalked it up to break-in but it still happening.
When the pass conditions are bad (and lately they have been as bad as January) I'll use Auto 4WD, and when things become completely snow covered, switch to 4-Hi going through Stevens. The entire trip between Auto and 4-Hi is roughly 20 to 30 miles depending on conditions. The uphill route is done with the engine under load due to the grade and I'll usually down shift to third to keep the transmission from hunting between OD and 3rd gear in the flatter parts of the switchbacks.
When I get out of truck after crossing the pass (or stopping to ski) I'll notice a burning smell. It seems to be coming from off of the exhaust system as it is stronger on the passenger side. I've stuck my face down in the wheel wells to make sure I'm not dragging a stuck caliper (read about that issue) and it's not brakes. When driving there is no binding of gears, hum, noise, or strange behavior. I'm not going over 45 MPH when I'm using Auto 4WD or 4-Hi (following the flow of the traffic). Usually when I hit the sheet of ice they call a parking lot at Stevens I'll use 4-Hi there.
I don't notice this smell when I drive around day to day in 2-Hi. The smell is not entering the cabin but is strong outside the vehicle at the rear, and strongest on the exhuast side. No carbon deposits on the cladding, and no oil smoke from the exhaust. Thoughts on what this might be (vehicle info is in sig file below)...
